crinoline

Crinoline is a stiffened fabric or hoop-based structure used in fashion to shape and support a skirt, creating a full and structured silhouette. Popular in the 19th century, especially during the Victorian era, it often consists of a series of metal or horsehair hoops worn under the dress to hold it outward and away from the body. Crinolines allowed skirts to achieve an elegant, voluminous appearance without heavy fabric. Today, the term may also refer to similar supportive or shaping garments designed to enhance the curvature or fullness of a skirt or dress.
