What is a "frock"?

A frock is a loosely fitted dress that hangs straight from the shoulder and typically has a gathered or pleated skirt. The term "frock" was commonly used in the 18th and 19th centuries to refer to a woman's dress, and it was often made of a lightweight fabric such as cotton or silk. Over time, the term has evolved to refer to various styles of dresses, including those with a fitted bodice and flared skirt, as well as those with a more relaxed, flowing silhouette. Frock dresses can be worn for both formal and informal occasions, depending on the fabric, cut, and style of the dress.
