How do you identify a cocktail dress?

To identify a cocktail dress, first look at the hemline. Typically, hemlines for cocktail dresses fall to the mid-thigh or above. Materials and embellishments can also indicate a cocktail dress. For example, fine fibers like silk, chiffon and velvet are commonly used for cocktail dresses, and many pieces feature decorative accents, such as sequins and rhinestones. Keep in mind that there are no real hard and fast rules for what classifies as a cocktail dress. The term generally refers to any dress slightly more casual than a formal full-length gown but still suitable for nighttime wear. Explore a large selection of cocktail dresses on 1stDibs.
