Crinoline is a stiffened or structured fabric used to support the shape of a garment, particularly skirts and dresses. It was originally made from horsehair and cotton, but modern versions often use synthetic materials. Crinolines became popular in the mid-19th century, especially in women's fashion, to create a voluminous silhouette that emphasized the waist and enhanced the overall shape of the dress. The use of crinoline peaked during the Victorian era, influencing styles such as the hoop skirt and the bustle. While crinolines are less common in contemporary fashion, they are still used in formal wear, such as wedding dresses, to achieve a dramatic and elegant look.
