DRESS CODE: SEMI-FORMAL ATTIRE FOR WOMEN AND MEN

Semi-Formal attire stands gracefully between casual charm and full-on elegance — the perfect balance of polish and personality. It’s the dress code that whispers refinement without shouting formality. Think of it as your go-to for occasions that call for a touch of sparkle but still allow you to move, laugh, and dance freely.

If "Formal Attire" is an opera evening and "Cocktail Attire" a night of city lights and clinking glasses, "Semi-Formal" is the in-between realm of confident elegance — an invitation to look your best without the stiffness of ball gowns or tuxedos.

Before you choose your outfit, remember: even the most beautiful dress or suit shines brightest when it complements your unique shape and proportions. StyleUp’s Body Shape Guide can help you identify which silhouettes truly enhance your natural lines — an investment that pays off every time you step into an event feeling effortlessly stunning.

1. What Is Semi-Formal Attire?

Semi-Formal attire is the art of balancing sophistication with ease. It’s a step up from business casual, yet less ceremonial than formalwear. You’ll most often see it requested for weddings, elegant dinners, theatre nights, or corporate events — places where your look should say polished and intentional without crossing into overly grand.

For women, this often means knee-length or midi dresses, sleek jumpsuits, or chic separates made of refined fabrics like satin, chiffon, lace, or silk. For men, it means tailored trousers, blazers, dress shirts, and refined footwear — sometimes with a tie, sometimes not, depending on the occasion and time of day.

A semi-formal dress ends at or below the knee but never touches the floor. Once it sweeps the ground, you’ve crossed into formal territory.

Fabrics & Colors

Semi-formal materials lean toward luxury but remain comfortable: taffeta, chiffon, velvet, silk, satin, lace, or even soft cashmere blends.

• For daytime events, lighter fabrics and softer colors — pastels, floral patterns, or gentle neutrals — feel fresh and appropriate.
• For evenings, deeper shades like navy, plum, charcoal, or emerald lend the right sense of evening sophistication.

2. Semi-Formal vs. Business Casual vs. Cocktail vs. Formal or Black Tie Optional – What’s the Difference?

Knowing where semi-formal sits on the spectrum makes choosing your look easier — and more confident.

2. 1. Semi-Formal vs. Business Casual

Business casual is professional yet relaxed — chinos, blazers, and shirts that can transition from office to after-hours dinner.
Semi-formal, however, raises the bar. The fabrics are finer, the silhouettes sharper, and accessories more deliberate. You’d swap your office loafers for polished dress shoes, or your cotton blouse for satin or chiffon. It’s about intention and finish.

2. 2. Semi-Formal vs. Cocktail

Cocktail attire tends to sparkle — shorter hemlines, bolder details, and more glamorous touches, especially for evening events. Semi-formal can certainly overlap but usually stays a touch more restrained. You might wear sequins or metallic accents at night, but with a subtler approach — elegant rather than dazzling.

2. 3. Semi-Formal vs. Formal or Black Tie Optional

Formal attire is the realm of tuxedos, full-length gowns, and evening gloves. Semi-formal steps back from that level of grandeur. The goal is to look elegant and composed without the ceremony of black-tie formality.

In essence:

• Business Casual = polished comfort that says “ready for work.”
• Semi-Formal = refined balance that says “ready to celebrate.”
• Cocktail = playful sophistication that says “ready to sparkle.”
• Formal = full elegance that says “ready to make an entrance.”

3. Semi-Formal Attire – When to Wear It

You’ll typically encounter “semi-formal” on invitations to occasions that blend celebration and sophistication.

Some classic examples include:

• Weddings and engagement parties
• Holiday dinners or elegant family gatherings
• Theatre, opera, or ballet nights
• Corporate dinners and conferences
• Graduation ceremonies or award banquets
• Memorials or respectful formal occasions

Time of day matters too. A daytime semi-formal outfit leans toward lighter fabrics and colors, while evening attire calls for darker tones, richer textures, and perhaps a hint of sparkle.

4. Semi-Formal Attire for Women

Women have a wonderful advantage when it comes to semi-formal dressing — the range of options is broad, elegant, and endlessly expressive. From tailored separates to flowing dresses, the semi-formal code invites you to find a balance between polished and playful.

Before choosing what to wear, take a moment to understand what flatters your natural shape. A-line dresses may gracefully complement pear shapes, wrap silhouettes often highlight hourglass figures, and sleek jumpsuits can elongate the frame for petites. You can discover your perfect cuts and proportions with StyleUp’s Body Shape Guide — it’s the secret behind dressing confidently for every event.

4. 1. Semi-Formal Attire for Women – What to Wear

Dressing for a semi-formal occasion is an art of balance — a gentle dance between elegance and ease. You’re not expected to arrive in a ball gown, but neither should your look whisper “Sunday brunch.” Semi-formal attire for women celebrates sophistication with freedom, blending graceful silhouettes with fabrics that feel as nice as they look.

Think refined simplicity: midi or knee-length dresses in flattering cuts, luxurious yet lightweight fabrics such as chiffon, silk-blend, or crepe. A semi-formal dress should highlight your shape, not overpower it. If you’re unsure which silhouettes best enhance your figure, StyleUp’s Body Shape Guide can help you discover the cuts that truly complement your natural lines — it’s a small investment that pays off every time you open your wardrobe.

Choose colors that suit the time of day and the setting. Lighter shades and pastels are perfect for daytime garden parties or beach weddings, while deeper jewel tones and muted metallics glow beautifully under evening lights.

Remember, semi-formal doesn’t mean dull — playful textures, subtle draping, or a hint of shimmer can add personality without straying into “formal gala” territory.

4. 1. 1. Two-Piece Suits and Jumpsuits

Who says dresses get all the attention? Well-cut two-piece suits or tailored jumpsuits can be just as sophisticated — and often more comfortable. A softly structured blazer over sleek trousers in ivory, navy, or dusty rose can be wonderfully chic.

Opt for materials that move gracefully: linen blends for warmer months, or structured wool for autumn evenings. If you’re choosing a jumpsuit, ensure it cinches gently at the waist and elongates your frame — heels or pointed-toe flats will help perfect the look.

4. 1. 2. Jackets

A well-chosen jacket completes a semi-formal outfit like the final brushstroke of a painting. For daytime, consider light blazers or cropped jackets in breathable fabrics; for cooler nights, go with a tailored coat or shawl in rich tones. Blazers in cream, soft grey, or pastel hues are timeless.

And here’s a tip from our stylists — choose a jacket shape that complements your body proportions. For example, women with hourglass or pear-shaped figures often shine in blazers that define the waist, while straight-cut or boxy styles can bring structure to rounder or more petite shapes.

4. 1. 3. Blouses

When paired with elegant trousers or skirts, a silk or satin blouse brings instant polish. Opt for minimal patterns or subtle lace detailing, avoiding anything too sheer or overly embellished. Pastel tones like blush, champagne, and sky blue work beautifully for daytime; deeper hues like emerald or navy transition easily into the evening.

If your blouse has dramatic sleeves or a statement neckline, balance it with simpler accessories — semi-formal dressing is all about harmony.

4. 1. 4. Skirts

A-line, pencil, or flowy midi skirts — all have their place in a semi-formal wardrobe. The key lies in the fabric and fit. Choose skirts that hold their shape yet move elegantly when you walk. A pleated midi skirt in satin, for example, pairs wonderfully with a fitted blouse or tucked-in knit top.

Length is crucial — mini skirts tend to read too casual, while floor-length skirts may feel overly formal unless styled carefully. Aim for knee to mid-calf length for that perfect semi-formal equilibrium.

4. 1. 5. Dresses

The semi-formal dress is the quiet heroine of countless celebrations. Midi or tea-length dresses are your safest and most versatile options, exuding grace without overstatement.

• For daytime events, flowy floral prints or pastels in light fabrics like cotton-silk blends or chiffon are delightful.
• For evening occasions, opt for more structured fabrics or richer tones like burgundy, navy, or forest green.

Avoid heavy embellishments or sequins reserved for black-tie affairs — instead, let subtle details such as a ruffle hem, delicate lace trim, or asymmetric neckline do the talking.

Sleeveless or off-shoulder designs can feel fresh and modern, but if the weather calls for it, a light wrap or tailored blazer adds sophistication.

4. 1. 6. Pants

Dress pants can be a stunning alternative to skirts or dresses — especially when they fit just right. Opt for cigarette pants, wide-leg trousers, or cropped tailored styles in refined materials like crepe or fine wool.

Neutral tones such as cream, grey, or black always work, but don’t shy away from soft color palettes either — pale pink or muted teal can add individuality without breaking dress code norms.

High-waisted cuts elongate the legs beautifully, especially when paired with heels.

4. 1. 7. Shoes

Your shoes should whisper elegance, not scream for attention. Classic pumps, kitten heels, or strappy sandals are perfect companions to semi-formal attire.

For daytime outdoor events, wedges or block heels provide comfort without sacrificing polish. Avoid overly casual footwear like flip-flops or chunky sneakers — and keep stilettos for more formal soirées.

If you know you’ll be walking or standing often, choose shoes with supportive soles — style is never worth sore feet.

4. 1. 8. Accessories

Accessories are your opportunity to add sparkle and personality — just remember that less is often more.

Simple gold or silver jewelry adds refinement without overshadowing your outfit. A minimalist clutch or small structured handbag complements the semi-formal aesthetic better than oversized totes.

A silk scarf or delicate belt can add definition, while understated earrings or a dainty pendant complete the look beautifully.

If you’re attending an outdoor event, consider a wide-brimmed hat for sun protection — practical and stylish.

4. 1. 9. Makeup & Hair

Think fresh, polished, and effortless. Semi-formal makeup should enhance your natural beauty — soft foundation, neutral tones, and a hint of color on the lips or cheeks.

For daytime, light and luminous works best; for evening, a deeper lip or a touch of shimmer on the eyelids adds quiet glamour.

Hair can be styled into loose waves, a sleek ponytail, or an elegant updo — choose something that complements both your outfit and the formality of the event.

4. 1. 10. Pantyhose & Ties

While pantyhose aren’t mandatory, sheer nude or black tights can lend a refined finish, particularly in cooler weather or more traditional settings.

As for ties — they belong more in the men’s section, but women wearing suits or androgynous styles can absolutely embrace them. A slim silk tie or neck bow in a soft shade can be a sophisticated nod to classic tailoring.

4. 2. Semi-Formal Outfit Inspiration for Women

Imagine arriving at a candlelit garden party in a flowing sage-green midi dress that sways with every step. Or picture yourself at an elegant indoor reception, wearing a tailored navy jumpsuit paired with gold hoops and suede pumps.

Semi-formal outfits thrive on contrast — they blend modern creativity with timeless restraint.

4. 2. 1. Below are some versatile ideas:

• Floral midi dress with nude heels and a soft cashmere shawl.
• Two-piece suit in cream with pearl earrings and a clutch in metallic tones.
• Sleeveless jumpsuit in deep blue with block heels and a statement bracelet.
• Pleated skirt and silk blouse for daytime weddings or work-related receptions.

4. 2. 2. Essential Items for Your Semi-Formal Wardrobe

• A versatile midi dress in a neutral or jewel tone.
• Tailored blazer that fits like a dream.
• Classic trousers with clean lines.
• Comfortable yet elegant shoes (pumps or block heels).
• Minimalist clutch and delicate jewelry.
• Soft wrap or shawl for transitional weather.
• Subtle makeup kit for touch-ups on the go.

4. 2. 3. Shopping List for Dress Code Semi-Formal – Women

• Dresses: midi, knee-length, or flowy silhouettes.
• Blouses: silk, satin, or elegant structured tops.
• Bottoms: tailored trousers, A-line or pleated skirts.
• Outerwear: cropped blazers, light coats, or wraps.
• Shoes: pumps, wedges, or heeled sandals.
• Accessories: clutches, pearl or gold jewelry, light scarves.
• Optional but elevating: a statement hairpin, silk gloves, or a fine wristwatch.

4. 3. Semi-Formal Attire for Women – What to Avoid

To keep your look in the perfect semi-formal lane, steer clear of extremes:

• Overly casual items like denim, sneakers, or cotton sundresses.
• Overly formal gowns with sequins, long trains, or metallic beading.
• Loud prints or neon tones that overshadow the setting.
• Bulky handbags or flashy accessories.

Your goal? To look polished, not pretentious; graceful, not overdressed.

5. Semi-Formal Attire for Men

Semi-formal attire for men sits gracefully between formal and business casual wear — polished, but not rigid; refined, yet still approachable. It’s the art of dressing smartly without the weight of ceremony.

This dress code is often requested for events like weddings, evening receptions, business dinners, or festive gatherings where full formal wear would feel excessive, but casual clothing would be out of place. Semi-formal dressing asks for thoughtfulness — the right fabrics, the right fit, and above all, the right balance between sophistication and ease.

Think of it as the elegant middle ground: you’re not in a tuxedo, but you’re certainly not in jeans. It’s about showing respect for the occasion while allowing your personal style to breathe.

5. 1. Semi-Formal Attire for Men – What to Wear

Semi-formal dress code is the quiet art of balance — a point where elegance meets ease, and formality blends with personality. It asks a man to be refined without being rigid, confident yet approachable. While formal attire demands strict adherence to rules, semi-formal style leaves just enough room for expression and comfort, inviting one to interpret tradition with subtle individuality.

5. 1. 1. The Suit – A Foundation of Polished Ease

A well-tailored suit remains the cornerstone of men’s semi-formal wear. It should neither whisper “business meeting” nor shout “black-tie gala,” but rather strike that comfortable note between the two. Opt for a single-breasted suit in navy, charcoal, or deep forest green for evenings, and lighter shades such as sand, taupe, or light grey for daytime events.

The texture of the fabric matters as much as the color. Smooth wool blends, lightweight twill, or soft cotton-silk mixes create a graceful drape and keep the silhouette elegant yet breathable. A crisp fit — shoulders aligned, sleeves ending just above the wristbone, and trousers with a gentle break — defines the semi-formal ideal: understated precision.

If the event leans toward the relaxed side of semi-formal, a blazer paired with tailored trousers offers sophistication without the full structure of a suit. Patterns like subtle checks or herringbone can be used to infuse quiet character without crossing into casual territory.

5. 1. 2. Shirts – The Canvas of Refinement

The shirt sets the tone. For most semi-formal occasions, a collared dress shirt in a solid hue is the safest and most stylish option. White remains timeless, light blue effortlessly versatile, and pastel tones — lilac, mint, or blush — ideal for daytime or spring gatherings.

Fabrics like fine cotton poplin or sateen add a soft sheen suitable for semi-formal elegance. Avoid overly shiny or heavily textured materials, as they can shift the balance toward evening glamour rather than refined sophistication.

Patterns should remain discreet — slim stripes, microdots, or delicate checks — to complement rather than compete with the rest of the outfit. A well-pressed shirt, structured collar, and cuffs that peek modestly beneath the jacket sleeves are the signs of quiet mastery.

5. 1. 3. The Tie – Optional but Powerful

In semi-formal wear, the tie is a choice, not a rule. It depends on the time of day, the setting, and the desired impression. For events leaning formal — weddings, ceremonies, or evening dinners — a silk tie in a deep, solid color or a restrained pattern adds authority and polish.

For daytime or creative environments, an open collar conveys confidence and ease without neglecting refinement. Alternatively, a knitted tie or one in matte fabric such as linen or wool can bridge the gap between relaxed and refined.

Bow ties are less common but may be worn for personality-driven occasions or artistic events — provided the rest of the outfit remains elegantly balanced.

5. 1. 4. Belts and Shoes – The Unspoken Structure

In semi-formal dressing, accessories like belts and shoes quietly anchor the entire look. Leather should always match in tone — black with black, brown with brown, tan with tan. A sleek belt with a simple metallic buckle complements rather than distracts.

Dress shoes complete the statement. Oxfords, Derbies, or loafers in polished leather or suede are ideal choices. Black offers formality and gravitas, brown brings warmth and flexibility, and burgundy adds subtle flair without ostentation.

For summer semi-formal events, suede loafers in muted shades (such as sand or slate blue) pair well with lighter suits. Avoid sneakers or overly casual slip-ons; they dilute the essence of semi-formal balance.

5. 1. 5. Socks – A Detail of Distinction

Though often overlooked, socks speak volumes. In semi-formal settings, they should bridge trousers and shoes seamlessly. Classic choices like black, charcoal, or navy remain safest for evening, while patterns such as discreet argyle or pin dots can enliven daytime ensembles.

For those inclined toward personality, a splash of color — deep burgundy, forest green, or rust — adds warmth, provided it complements rather than competes. The cardinal rule: never reveal bare ankles at semi-formal events unless specifically appropriate in warm-weather outdoor settings.

5. 1. 6. Accessories – The Finishing Notes

Accessories in semi-formal wear should whisper, not shout. A pocket square, whether crisp white or softly patterned, lends polish. Cufflinks, if worn, should be understated — silver, brushed gold, or black enamel.

A wristwatch with a leather strap balances practicality and style; metallic watches tend to feel slightly more formal. Avoid anything oversized or overly sporty.

If the event allows for subtle expression, a lapel pin or tie bar adds a final touch of personality. Think of accessories not as decoration but as punctuation — refined pauses in the composition of one’s look.

5. 2. Outfit Inspiration & Seasonal Guidance for Men

Semi-formal attire for men evolves gracefully with the seasons — what stays constant is elegance; what shifts is texture, tone, and layering. The beauty of this dress code lies in its adaptability: it allows men to stay refined through warmth or chill, daylight or candlelight.

5. 2. 1. Spring – Fresh Tones and Light Fabrics

As nature reawakens, so can your wardrobe. Spring semi-formal dressing is about lightness — both in mood and in material. Opt for suits in pale grey, light navy, or sand, crafted from breathable fabrics like cotton blends, linen, or lightweight wool. Shirts in soft pastels such as sky blue, lilac, or sage echo the season’s freshness.

Accessories can be subtly playful — a floral pocket square, a woven belt, or suede loafers in tan or taupe. It’s the perfect moment to exchange heavy leather soles for lighter constructions and to introduce color without overstatement.

5. 2. 2. Summer – Refined Ease

Summer semi-formal wear should look effortless but intentional. The key is maintaining a polished silhouette while staying cool. Lightweight suits in beige, ivory, or light blue — preferably in linen or linen-blend — are ideal for daytime or outdoor events.

Skip the tie if the event allows; unbutton the top collar, roll your sleeves slightly, and choose loafers without socks (only if the setting is relaxed). Sunglasses and a watch with a woven or leather strap complete the look — discreetly stylish, never flashy.

For evening events, shift toward mid-tone suits (dusty blue, tobacco, olive) and finer weaves. A silk pocket square in deeper hues bridges the transition from daylight to dusk.

5. 2. 3. Autumn – Depth and Texture

Autumn invites warmth, texture, and richness. Replace lightweight fabrics with medium-weight wool, tweed, or brushed cotton. Earthy tones — chestnut, charcoal, forest green, or deep navy — create grounded sophistication.

Layering becomes both functional and stylish: a fine knit under a blazer or a wool waistcoat under a suit jacket adds depth without formality overload. Ties in matte textures (wool, cashmere, or knit) harmonize beautifully with the season’s tactile feel.

For footwear, darker shades — mahogany, oxblood, or black — anchor the outfit. It’s also the perfect time to introduce patterned socks or pocket squares in burnt orange, rust, or plum.

5. 2. 4. Winter – Elegance in Structure

Winter semi-formal dressing calls for gravitas. Structured suits in navy, charcoal, or midnight blue convey authority and warmth. Heavier fabrics like flannel, wool, or even velvet (for festive occasions) add a luxurious dimension.

A crisp white shirt, paired with a silk tie in deep jewel tones (burgundy, emerald, sapphire), elevates the ensemble. Layering a fine merino turtleneck under a suit can be a refined alternative to a shirt and tie for creative or evening settings.

Outerwear matters: a long wool overcoat, cashmere scarf, and leather gloves preserve both warmth and dignity. The winter semi-formal look should feel timeless — calm, composed, and impeccably considered.

5. 3. Shopping List for Semi-Formal Attire (Men)

To build a semi-formal wardrobe that works across seasons and occasions, invest in versatile, well-made pieces that mix and match effortlessly. Here’s a foundational checklist:

The Core Pieces

• 1–2 Tailored Suits – one in navy or charcoal for evening/formal settings, one in lighter tone (grey, sand, or beige) for daytime or warmer months.
• 1 Blazer + 2 Pairs of Tailored Trousers – for semi-formal events leaning slightly toward relaxed; mix textures for contrast.
• 3–4 Dress Shirts – white, light blue, and pastel hues; one patterned (fine stripes or checks) for variety.
• 1–2 Knit Layers – fine merino wool or cashmere sweaters to layer beneath blazers in cooler seasons.

Footwear

• 1 Pair of Oxfords or Derbies – polished leather, black or dark brown.
• 1 Pair of Loafers – suede or leather, in tan or burgundy for warmer months.
• Optional: Monk straps for modern flair or brogues for texture.

Accessories

• 2–3 Ties – silk for formal events, knit or matte wool for smart-casual semi-formal occasions.
• Pocket Squares – one crisp white and one patterned (paisley, dots, or florals).
• Leather Belt – matching your primary shoe color.
• Dress Watch – minimal face, leather strap, understated design.
• Cufflinks (optional) – silver or brushed gold, discreet and classic.

Seasonal Additions

• Lightweight Linen Suit (summer)
• Wool or Tweed Blazer (autumn/winter)
• Overcoat & Scarf (winter) – neutral shades like camel, navy, or charcoal.
• Sunglasses & Lightweight Loafers (spring/summer)

5. 4. Semi-Formal Attire for Men – What to Avoid 

While semi-formal allows for flexibility, it is not a space for casual shortcuts. A few missteps can easily pull an outfit from refined to careless — so here’s what to steer clear of:

• No jeans or chinos, regardless of how tailored they are. Semi-formal dressing always calls for proper trousers or a suit.
• Avoid sneakers or casual shoes. Even minimalist leather sneakers are too relaxed; choose loafers, Oxfords, or Derbies instead.
• Skip bold prints and loud colors. Semi-formal attire thrives on subtlety — classic tones and refined details make a stronger impression than statement patterns.
• No short-sleeved shirts. A proper dress shirt or long-sleeved button-up is the foundation of a smart look.
• Leave casual accessories at home. This includes canvas belts, sport watches, or oversized fashion jewelry. Opt for polished, understated pieces that speak quietly of elegance.
• Avoid unstructured, wrinkled fabrics. Iron or steam your outfit; a semi-formal look must appear deliberate, not improvised.
• Never mix too many informal elements. For example: blazer + jeans + sneakers might work for smart casual, but not here. The semi-formal code is a refined midpoint, not an experimental playground.

Think of semi-formal as the art of balance: your look should never seem overdressed — yet always more composed than casual.

6. Semi-Formal Dress Code For Women and Men – Quick Summary

For both men and women, semi-formal attire bridges the gap between formal eveningwear and smart casual. It offers structure without stiffness and sophistication without extravagance — perfect for weddings, receptions, cocktail dinners, or elegant corporate events that don’t demand black tie.

• Men: A semi-formal look for men usually means a tailored suit or blazer with dress trousers, a collared shirt, and dress shoes. A tie is optional but often recommended for evening or more formal occasions. Fit, fabric, and polish define the success of the look.
• Women: For women, semi-formal can range from midi or knee-length dresses to elegant separates such as a blouse with tailored trousers or a skirt. Fabrics like silk, chiffon, crepe, or fine wool convey understated sophistication. Heels, refined flats, or dressy ankle boots complete the outfit.

Semi-Formal Dress Code – Key Points

Men:

• Opt for a suit or smart blazer-and-trousers combination.
• Stick to neutral, mid, or dark tones — navy, grey, charcoal, taupe.
• Choose polished shoes — Oxfords, Derbies, or loafers.
• Keep shirts crisp, long-sleeved, and well-fitted.
• Accessories should enhance, not dominate: a watch, pocket square, and belt are enough.
• Seasonal adaptation is welcome — lighter suits in summer, textured fabrics in autumn and winter.

Women:

• Choose elegant midi or knee-length dresses, or mix-and-match chic separates.
• Avoid full-length gowns (too formal) and mini dresses (too casual).
• Go for refined fabrics — silk, crepe, lace, or tailored wool.
• Accessorize tastefully: delicate jewelry, a structured clutch, and shoes that balance comfort with grace.
• For colder seasons, add a tailored blazer, shawl, or elegant coat.

Both:

• Elegance without excess is the guiding rule.
• Clothes should fit perfectly and look intentional.
• Pay attention to grooming, posture, and presence — the subtler side of semi-formal refinement.
• Always tailor your outfit to the time and setting of the event (day vs. evening).
• Remember: confidence is the final accessory.

Aim:

To appear refined, confident, and effortlessly polished — someone who respects the occasion but remains comfortable in their own style.

Perfect For:

Weddings, receptions, evening dinners, upscale networking events, milestone celebrations, and other gatherings that call for graceful sophistication without black-tie formality.
