Crinoline was originally a stiff fabric with a weft of horse-hair and a warp of cotton or linen thread. The fabric first appeared around 1830, but by 1850 the word had come to mean a stiffened petticoat or rigid skirt-shaped structure of steel designed to support the skirts of a woman’s dress into the required shape.

Crinolines are still worn today. They are usually part of a formal outfit, such as an evening gown or a wedding dress. The volume of the skirt is not as great as during the Victorian era, so modern crinolines are most often constructed of several layers of stiff net, with flounces to extend the skirt. If there is a hoop in the crinoline, it will probably be made of plastic or nylon, which are low in cost, lightweight and flexible.
