What Is Cocktail Attire?

Cocktail style strikes the balance between polished and playful, with just the right personality. It’s a popular dress code for weddings and formal events, bridging the gap between formal and casual. Think shorter hemlines (mid-thigh to ankle), matching sets in luxurious fabrics, and elevated accessories.

Three Rules to Follow

Stay away from loud on loud. You never want to look like you’re trying too hard, so avoid a statement dress and bold accessories and heavy makeup. Keep one element simple and pair it with something more elevated to accomplish that true cocktail look.
Pick one part of your outfit to stand out. For instance, if you’re wearing a colorful designer dress, keep it grounded with a simple slingback or nude strappy sandal. Showing off a sequined clutch? Let it shine against a solid dress and neutral heels that elongate the leg.
Do the same for hair and makeup. If you’re doing a French twist up-do, keep everything else natural. That restraint reads as effortless taste—and that’s the kind of elegance that never goes out of style.

A Brief History of Cocktail Attire

People have been wearing cocktail attire since the roaring ‘20s. However, the term “cocktail dress” was coined by Christian Dior in the late 1940s. According to the MET, he used the term to enchant wealthy Americans with fashion-forward, waist-defining looks—beloved by style icons like Grace Kelly and Audrey Hepburn—to wear while hosting parties.

What Is Cocktail Attire for a Wedding?

First thing’s first, make sure you’re wearing the right color. Avoid wearing white or something that would look white on camera like pale pastels, and stay away from red (it’s not approved for wedding guests in some traditions). Another tip: think about the bride and her own personal style. If her style’s reserved, don’t go for a loud jumpsuit or a body-hugging dress. If she’s more fashion-forward, there’s room to have fun with it. If there’s a theme to the wedding, wear what you feel fits the request. Consider the vibe of the location for a beach or coastal wedding, think classic holiday for festive cocktail attire, and dress in florals for a garden party.

Dos and Don’ts

Do choose elevated fabrics. Think silk, velvet, satin, crepe—these textures instantly make an outfit feel more refined and event-appropriate. They also tend to photograph better and move beautifully.

Don’t go overboard with trends or textures. Less is more!

Do wear black—it's timeless, elegant, and always appropriate. Plus, you’ll likely be able to wear it again! The LBD is cocktail’s north star. It’s endlessly adaptable and always appropriate.

Don’t wait until the last minute to plan your outfit. A well-thought-out look always feels (and looks) more confident.

Do tailor your look. A well-fitting outfit changes everything. Even the most beautiful dress can fall flat without the right shape. Most pieces need at least one small adjustment—take the time, it’s always worth it.

Do treat yourself to a blowout. Polished hair brings the whole look together. Even a low-key outfit can feel elevated with fresh, healthy-looking hair. Pro tip: For a smooth, bouncy blowout, show your stylist a photo of Jennifer Aniston. Ask for volume in the back only—not the crown.

Cocktail Attire for Her

Dress to impress with these four classic cocktail styles that always look good, no matter your plans.

Cocktail Dresses

Always say yes to a cocktail dress. The best length? At or below the knee and above the ankle. Whether you lean minimalist or full glamour, the accessories tell the story.

Jumpsuits

A sleek jumpsuit can be just as sophisticated as a dress, especially in the right fabric. What makes it cocktail is the level of finish: luxe materials, proper fit, and confidence in the styling!

Matching Sets

Sets are put-together with minimal effort. The same rules apply to a set as they do for a jumpsuit: think about the fabric and styling. Our current obsession: party pajamas.

Elevated Separates

Yes, your tops and bottoms can feel dressy! It’s down to the material and the styling. Try a velvet blazer with a metallic skirt or feathered pants with a button down. It’s up to you.

Cocktail Attire for Him

Cocktail attire for men is not as straightforward as a black-tie dress code. It’s best to go with a suit, tie, and polished dress shoes. For a more casual look, a button down and nice slacks will do the trick. And don’t forget dress socks!

The Finishing Touches

Cocktail dressing isn’t about having a dozen statement pieces—it’s about the right ones, always ready. With a classic black heel, a strappy sandal, a metallic evening bag, diamond studs, and a statement cuff, you’re set. Everything else is layering in personality.
