If cocktail attire is the requested dress code for an upcoming wedding, that leaves a lot of room for interpretation as a wedding guest. Cocktail attire falls between formal and casual and often translates to midi and knee-length dresses. Yet, depending on the venue, season, and even time of day of the wedding, you can get by with different lengths and fabrics.
To help you find an outfit you love and feel confident showing up in, we researched the best cocktail dresses available online. We ensured our list covers all wedding destinations, seasons, and themes. We also looked for wide size ranges, fabrics, silhouettes, and sleeve styles. Most importantly, we looked for versatile designs you can—and will want to—wear again.

What to Look for in Cocktail Attire
- Season: Cocktail attire is usually worn to semi-formal and formal weddings, so you’ll want to consider a few things. First, what season is the wedding? If it’s in the spring or summer, bright colors, playful prints, and pastel shades are idyllic. Cotton fabric will keep you cool during a summer wedding. For the fall and winter, you can gravitate towards heavier fabrics and jewel tones.
- Venue: Next, consider what type of venue it is. For an outdoor wedding, you can easily get away with light, floaty fabrics such as cotton, eyelet lace, jersey, or chiffon. If the wedding is in a banquet hall or a historic building, elegant fabrics like satin, velvet, and taffeta are perfectly polished. A classic slip dress is also ideal for these indoor weddings. Beading and sequins in a shorter length can also work well for a classy cocktail look.
- Time of Day: Lastly, think about the time of day the ceremony will be held. In the morning or early afternoon, a slightly more casual dress is entirely appropriate. For an evening ceremony, you can step up your little black dress with feathered accents or beading.
