Definition
A petticoat is a skirt-like garment worn underneath a dress or skirt to give it extra fullness or shape. It can be made of various materials, like cotton, linen, or synthetic fabrics. Think of it as a secret weapon for achieving that perfect silhouette.ð Petticoats were particularly popular in historical fashion, especially during the Victorian era and the 1950s. While less common today, they're still used in formal wear, historical reenactments, and some vintage-inspired styles. It's basically the unsung hero of a voluminous skirt.
