If cocktail attire was the requested dress code for an upcoming wedding, that could leave a lot of room for interpretation as a wedding guest. According to wedding experts, 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.
A midi dress that hits at the knee is a popular choice for cocktail wedding guest attire.

We ensured our list covers all wedding destinations, seasons, and themes. We also looked for styles in wide size ranges, various fabrics, and silhouettes.

What to Look for in Cocktail Attire
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. Not only does Farm Rio Midi Sundress come in a vivid print, but the cotton fabric will keep you cool during a summer wedding. For the fall and winter, you can gravitate towards heavier fabrics and jewel tones, like Fame & Partners Satin Shay Dress.
Next, consider what type of venue it is. For an outdoor wedding, you can easily get away with light, floaty fabrics like 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, like this one from BHLDN, is ideal for these indoor weddings. Beading and sequins in a shorter length, like this sparkly dress from Retrofete, 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. We can totally see guests wearing this loose maxi design from LoveShackFancy for a garden or beach wedding during the daytime. For an evening ceremony, you can step up your light black dress with feathered accents like in LPA Aurora Dress.
What is a cocktail dress?
Cocktail attire is a delicate balance between formal and casual, as well as elegant and comfortable. For ladies, that typically equates to a midi or mini-length dress and heels.
What is an appropriate dress length for a cocktail dress?
Knee-length is great, though it can vary. As a general rule, try to avoid wearing anything that's too short, tight, or low cut. While cocktail attire offers more freedom to play with colors, prints, materials, and length, it's still nice to find something classy and elegant for a formal wedding. You can even wear a maxi, but in this case, it’s best to opt for a more casual fabric.
Can I wear a cocktail dress to a black-tie wedding?
A black-tie dress code tends to be more formal than cocktail attire, and therefore typically requires floor-length gowns.
