Wedding Guest Dress Code Guide

From white tie to beach and destination weddings — understand length, fabric, color, silhouette, shoes, and what to avoid. Each section includes curated, in-stock dress picks mapped to our catalog attributes.

Dress code

White Tie

The most formal evening code — floor-length gowns, refined fabrics, and black or jewel-tone polish.

Shop this dress code

White tie is the highest formal dress code for galas, state dinners, and ultra-formal balls. Guests should aim for full-length eveningwear with elevated fabrics and minimal daytime details.

Length

Floor-length only. Ball gowns and elegant column gowns are ideal. Tea-length, midi, and mini are too casual for white tie.

Materials & fabrics

Silk, satin, velvet, heavy crepe, organza, and fine chiffon. Look for couture-level drape and clean finishes. Avoid cotton jersey and linen.

Colors

Deep jewel tones, classic black, midnight navy, emerald, ruby, champagne metallics. Soft pastels work only if the fabric is evening-weight. Skip bright daytime florals.

Silhouette

Ball gown, A-line with volume, or sleek column/mermaid with formal structure. Dramatic but refined necklines and sleeves are welcome.

Shoes & accessories

Closed-toe evening heels, satin or silk pumps, or elegant embellished sandals with a high formal finish. Clutch handbags only.

What to avoid

Cocktail length, casual fabrics, white/ivory bridal looks, loud logos, sneakers, daytime sun dresses, and overly sheer partywear without lining.

Quick tips

  • Confirm the invitation wording — “white tie” is rarer than black tie.
  • A polished updo and statement earrings complete the look without competing with the gown.

Dress code

Black Tie

Formal evening glamour — floor-length or refined formal midi, elevated fabric, evening accessories.

Shop this dress code

Black tie signals formal eveningwear for weddings, charity galas, and upscale receptions. Choose a polished gown or sophisticated formal dress with evening fabrics.

Length

Floor-length is safest. A refined formal midi or tea-length can work for fashion-forward events if fabric and silhouette feel evening-ready.

Materials & fabrics

Silk, satin, velvet, chiffon, crepe, lace overlays, sequin or beading used with restraint. Avoid denim, cotton jersey, and casual knits.

Colors

Black, navy, emerald, burgundy, deep plum, metallics, and sophisticated jewel tones. Soft neutrals work in luxe fabrics. Avoid pure bridal white.

Silhouette

Column, mermaid, A-line evening gown, structured sheath, or soft ball-gown volume. Clean lines read more formal than ruffles-heavy day dresses.

Shoes & accessories

Heeled evening sandals, pointed pumps, or elegant strappy heels. Metallic or black satin is classic. Skip chunky boots and flats unless mobility requires them.

What to avoid

Short party dresses, casual maxis, white bridal silhouettes, logo belts, backpacks, and overly revealing styles that feel clubwear.

Quick tips

  • If the venue is outdoor after dark, bring a wrap or light evening jacket.
  • Jewelry can be bolder than daytime — one strong piece is enough.

Dress code

Black-Tie Optional

Dress up toward black tie — formal gowns preferred, polished cocktail or formal midi accepted.

Shop this dress code

Black-tie optional means formal is encouraged but not mandatory. Aim for the elevated end of cocktail-to-formal so you never look underdressed next to true black-tie guests.

Length

Floor-length or a sophisticated midi/tea-length. Mini lengths are usually too short unless the silhouette is clearly formal.

Materials & fabrics

Silk blends, satin, crepe, chiffon, velvet, lace. Slight sheen or refined texture elevates the look. Avoid casual cotton and linen separates that read daytime.

Colors

Jewel tones, black, navy, champagne, muted metallics, deep florals on evening fabric. Soft pastels work if the cut is formal.

Silhouette

Evening A-line, column, wrap gown, structured cocktail dress, or sleek sheath with formal details (cowl, capelet, statement sleeve).

Shoes & accessories

Heels or dressy block heels. Elegant sandals or closed-toe pumps. A polished clutch finishes the look.

What to avoid

Business separates that look office-ready, casual maxis, sneakers, denim, and anything you’d wear to brunch.

Quick tips

  • When unsure, choose the dressier option — black-tie optional rewards “slightly over” more than “slightly under.”
  • A formal midi in satin often hits the sweet spot.

Dress code

Formal

Elevated evening or ceremony wear — polished length, refined fabric, intentional accessories.

Shop this dress code

Formal sits just below black tie. It’s common for evening weddings, hotel ballrooms, and upscale dinners. Prioritize polished silhouettes and dressier fabrics over trendy casual pieces.

Length

Floor-length, midi, or tea-length. Mini only if very polished and invitation culture allows; when unsure, go longer.

Materials & fabrics

Crepe, silk, satin, chiffon, lace, structured suiting fabrics for dressier co-ords. Avoid casual knits, terry, and linen beachwear.

Colors

Navy, black, emerald, wine, slate, blush, champagne, and refined prints. Skip neon and beachy brights.

Silhouette

Sheath, A-line, column, soft mermaid, or elegant wrap. Structured shoulders and clean waist definition read formal.

Shoes & accessories

Pumps, slingbacks, dressy heels, or elegant flats for outdoor formals. Keep handbags structured or clutch-sized.

What to avoid

Daytime floral sundresses, jumpsuits that look loungewear, white bridal silhouettes, and sporty shoes.

Quick tips

  • A tailored wrap or cropped jacket elevates a formal midi for cooler venues.
  • Match metal tones in jewelry and shoes for a cohesive formal finish.

Dress code

Cocktail

The wedding-guest sweet spot — knee to midi length, dressy fabric, party-ready polish.

Shop this dress code

Cocktail is the most common wedding-guest code in the US. Choose a dressy dress between knee and midi length with elevated fabric and intentional accessories — more festive than office wear, less rigid than black tie.

Length

Knee-length to midi is classic. Tea-length works well. Floor-length is optional for evening cocktail; mini can work if sophisticated.

Materials & fabrics

Crepe, satin, chiffon, lace, mikado, velvet (seasonal), jacquard. Avoid cotton t-shirt knits and denim.

Colors

Almost any refined color: jewel tones, pastels, metallics, subtle prints. Avoid pure white/ivory bridal looks and neon club colors.

Silhouette

Fit-and-flare, sheath, A-line, wrap, slip dress with structure, or soft peplum. Movement-friendly for dancing is a plus.

Shoes & accessories

Heels, dressy block heels, elegant mules. Strappy sandals for warmer months; closed toe for cooler evenings.

What to avoid

Business sheath with no party detail, overly casual maxis, white bridal gowns, sneakers, and oversized day bags.

Quick tips

  • If the couple’s palette is shared, stay complementary — not matching the wedding party.
  • A bold earring or metallic shoe can upgrade a simple cocktail dress instantly.

Dress code

Semi-Formal

Dressy but relaxed — midi and polished shorter lengths, softer fabrics, easy elegance.

Shop this dress code

Semi-formal sits between cocktail and dressy casual. Think wedding-appropriate dresses without full evening glamour — ideal for afternoon receptions and many hotel ceremonies.

Length

Midi, knee, or tea-length preferred. Floor-length is fine if light and not overly formal. Mini only if modest and polished.

Materials & fabrics

Crepe, chiffon, soft satin, lace mixes, quality jersey with structure. Linen blends can work for daytime semi-formal in warm climates.

Colors

Soft neutrals, pastels, mid-tone jewel shades, subtle prints. Avoid harsh neon and bridal white.

Silhouette

A-line, wrap, fit-and-flare, soft sheath, shirt-dress elevated with fabric and accessories.

Shoes & accessories

Block heels, low heels, dressy flats, polished sandals. Comfort matters for outdoor photos and longer ceremonies.

What to avoid

Jeans, t-shirts, athletic wear, beach cover-ups, and anything that looks like office attire without dressy details.

Quick tips

  • Layer a blazer or wrap for cooler church-to-reception transitions.
  • Semi-formal still benefits from intentional jewelry and a put-together hairstyle.

Dress code

Dressy Casual

Intentional casual — nice dresses or elevated separates, polished shoes, no gym or beachwear.

Shop this dress code

Dressy casual (sometimes “smart casual”) asks for a put-together look without cocktail-level formality. Choose a nice day dress, jumpsuit, or elevated separates that photograph well for a wedding.

Length

Midi and knee-length dresses are ideal. Maxi can work if lightweight and polished. Avoid very short minis and lounge-length hems.

Materials & fabrics

Cotton blends with structure, linen blends, soft crepe, lightweight knits with polish, eyelet, subtle embroidery. Avoid sweatpants fabrics and distressed denim.

Colors

Seasonal colors, soft prints, earth tones, pastels, navy. Keep white/ivory minimal so you don’t compete with the couple.

Silhouette

Easy A-line, shirt-dress, wrap, midi slip with cardigan, tailored jumpsuit, or polished co-ord set.

Shoes & accessories

Dressy flats, block heels, clean sandals, loafers. Skip flip-flops and running shoes.

What to avoid

Gym wear, ripped jeans, graphic tees, beach cover-ups, baseball caps, and anything stained or wrinkled.

Quick tips

  • Accessories do the heavy lifting — a structured bag and simple jewelry make casual pieces feel intentional.
  • When the invitation says “dressy casual,” err slightly dressier if the venue is a restaurant or rooftop.

Dress code

Garden Wedding

Outdoor elegance — breathable fabrics, garden-friendly heels, soft color and print.

Shop this dress code

Garden weddings mix natural light, grass or gravel, and often daytime or golden-hour timing. Choose breathable fabrics, stable shoes, and colors that complement greenery without looking like a bridesmaid uniform.

Length

Midi and tea-length excel on grass. Maxi works if you can walk without dragging. Mini is fine for informal garden parties if modest.

Materials & fabrics

Chiffon, cotton-silk blends, lightweight crepe, linen blends, eyelet, soft lace. Avoid heavy velvet and long trains that pick up grass.

Colors

Florals, soft pastels, sage, dusty blue, lavender, butter yellow, soft prints. Deep jewel tones for evening gardens. Avoid stark white.

Silhouette

Flowy A-line, wrap, fit-and-flare, soft sheath. Movement and comfort matter for outdoor photos and standing cocktails.

Shoes & accessories

Block heels, wedges, stylish flats. Thin stilettos sink into lawns — choose platforms or wider heels for grass.

What to avoid

Heavy ball gowns, stilettos without support, all-black severe looks for daytime gardens (unless requested), and pure bridal white.

Quick tips

  • Pack a light wrap for temperature drops after sunset.
  • A midi floral in quality fabric is the garden-guest classic for a reason.

Dress code

Beach Wedding

Resort polish — flowy hems, sand-friendly shoes, light fabrics, refined color.

Shop this dress code

Beach weddings call for breathable, wind-friendly dresses and shoes that handle sand. Think resort formal or elevated resort casual depending on the invitation — never literal swimwear.

Length

Midi and lightweight maxi are ideal. Knee-length works for casual beach ceremonies. Avoid long trains that drag sand.

Materials & fabrics

Chiffon, georgette, lightweight cotton, linen blends, soft jersey with structure. Avoid stiff ballgown fabrics and heavy beading that heats up.

Colors

Ocean blues, soft coral, sand neutrals, tropical but refined prints, white-adjacent pastels carefully (avoid bridal white). Sunset jewel tones for evening beach.

Silhouette

Flowy A-line, wrap, soft slip with lining, lightweight fit-and-flare. Secure straps help with coastal wind.

Shoes & accessories

Dressy sandals, wedges, block heels, or barefoot-friendly dressy flats. Bring a second pair for boardwalks or indoor receptions.

What to avoid

Stilettos, heavy velvet, black-tie ball gowns (unless evening resort black tie), cover-ups as the only layer, and pure white bridal looks.

Quick tips

  • A lined dress prevents sheer surprises in bright coastal light.
  • Secure hair and choose earrings that won’t fly in the wind.

Dress code

Destination Wedding

Travel-smart elegance — packable fabrics, climate-aware layers, multi-event versatility.

Shop this dress code

Destination weddings often span welcome dinners, ceremony, and brunch. Prioritize packable dresses, climate-appropriate fabrics, and silhouettes that move from travel day to celebration without a full suitcase of formalwear.

Length

Follow the printed dress code for each event. Many destinations lean cocktail or semi-formal for ceremony and dressy casual for welcome drinks. Midi lengths travel especially well.

Materials & fabrics

Wrinkle-resistant crepe, jersey blends with structure, lightweight chiffon, packable satin. Avoid ultra-delicate beading that snags in luggage.

Colors

Seasonal colors for the destination climate, soft prints, versatile navy or jewel tones that photograph in multiple lights. Confirm cultural color customs for international venues.

Silhouette

Wrap, A-line, soft sheath, convertible styles, or two-piece sets that mix across events. Choose something you can sit in for travel and dance in at the reception.

Shoes & accessories

Packable heels or block heels, dressy flats for cobblestones, sandals for beach destinations. Always check terrain: villa lawn, city streets, or sand.

What to avoid

Overpacking rigid formals you won’t rewear, ignoring climate (heavy velvet in tropical heat), and assuming every event is the same dress code.

Quick tips

  • Read the full itinerary — welcome party and ceremony may have different codes.
  • A versatile midi plus one elevated evening piece covers most multi-day destination schedules.

Dress code FAQ

What is the difference between black tie and black-tie optional?

Black tie expects formal eveningwear (usually floor-length for women). Black-tie optional encourages formal looks but allows polished cocktail or formal midi dresses if you do not wear a full gown.

Can I wear white to a wedding as a guest?

In most US weddings, pure white and bridal ivory are reserved for the couple. Choose soft pastels, champagne, or other colors unless the couple has explicitly invited white attire.

What shoes work for garden or beach weddings?

For gardens, prefer block heels, wedges, or stylish flats that will not sink into grass. For beaches, choose dressy sandals or wedges and pack a second pair for hard surfaces.
