Cocktail dresses for every kind of evening.
Cocktail is the most common dress code in our catalog — more than 17,000 dresses across Nordstrom, ASOS, Revolve, Lulus, Reformation and more, all searchable in one place and ranked by relevance, never by who paid.
What counts as cocktail attire
Cocktail attire occupies the generous middle ground between a sundress and a gown. The formula: a knee-length or midi dress in a fabric with some polish — crepe, satin, chiffon, lace, or structured ponte — styled with heels or refined flats. It is the default code for evening wedding receptions, engagement parties, holiday parties, and most "semi-formal" invitations. The two edges to avoid are a floor-length gown, which overshoots into black-tie, and casual cotton, which undershoots the room. If the dress would work at a nice dinner but not at brunch, you have found cocktail.
Getting the length right
Length is the fastest formality signal a dress sends. Just-above-the-knee is the traditional cocktail standard and universally safe. The midi — hitting mid-calf — is its modern successor: more current, more forgiving in photos, and appropriate nearly everywhere cocktail is requested. Minis can absolutely work for birthday dinners and nights out, but at weddings and work-adjacent events they read party rather than polished. Our catalog skews mini and midi (24,000 and 17,000 styles respectively), so filtering by length is the quickest way to narrow a search.
Colors and seasonality
- The LBD: black is the largest color family in our catalog for good reason — one black cocktail dress restyles for years of events.
- Jewel tones: emerald, sapphire, and burgundy flatter nearly every complexion and own the fall and winter calendar.
- Spring and summer: dusty blue, soft pink, terracotta, and florals on a colored base — breathable chiffon and georgette keep them event-ready.
- Wedding receptions: all of the above except white, ivory, cream, and champagne — those stay with the bride.
- Metallics and sequins: holiday parties and New Year's Eve are their natural habitat; keep jewelry minimal and let the fabric talk.
Budget, honestly
Cocktail dresses have the widest price spread of any occasion — and the weakest link between price and how good you will look. ASOS and Lulus put genuinely sharp options under $100; Nordstrom and Revolve carry noticeably better fabric and construction between $150 and $350. Because a cocktail dress re-wears more than anything else in an event wardrobe, cost-per-wear math favors one excellent dress over several forgettable ones. Every result on DressMatcher links directly to the retailer's product page, so prices are always the retailer's own.

Cocktail dress questions, answered
What is cocktail attire for a woman?
Cocktail attire is the middle ground between casual and black-tie: a knee-length or midi dress in an elevated fabric such as crepe, satin, chiffon, or lace. It should feel dressed-up without being a gown — think evening reception, engagement party, or holiday party.
How long should a cocktail dress be?
The classic cocktail length runs from just above the knee to mid-calf. Knee-length is the traditional answer; a polished midi is its modern equivalent and often more versatile. Floor-length reads black-tie, and true minis lean party rather than cocktail — save them for less formal celebrations.
What color cocktail dress is most versatile?
Black remains the workhorse — the classic LBD moves from work event to wedding reception with an accessory change. Navy, emerald, and burgundy are close seconds and photograph richly. If the event is a wedding, skip white and ivory; those belong to the bride.
Can I wear a cocktail dress to a wedding?
Yes — cocktail dresses are exactly right for invitations reading “cocktail attire,” “semi-formal,” or “festive.” Choose richer fabrics for evening receptions and lighter colors or prints for daytime. For black-tie weddings, step up to a gown instead.
How much should a good cocktail dress cost?
The sweet spot is $60 to $200. ASOS and Lulus dominate under $100; Nordstrom and Revolve carry elevated fabrics and construction from $150 to $350. Since cocktail dresses re-wear more than any other occasion piece, cost-per-wear favors buying one great dress over three passable ones.
