Definition & Meaning of "petticoat"

What is a "petticoat"?

A petticoat is a type of women's undergarment that is worn underneath a skirt or dress to give it added volume and shape. It typically consists of several layers of fabric, such as cotton, nylon, or tulle, that are gathered at the waist and flare out to create a full, bell-shaped silhouette. Petticoats can be plain or decorated with lace, ruffles, or other embellishments, and are available in many colors and lengths. They may also be worn as a separate garment, without an outer skirt or dress, as a form of lingerie or sleepwear. Petticoats were commonly worn in the past and are still used today in certain styles of fashion, such as vintage and retro-inspired clothing.
