A hoop skirt, also known as a crinoline, is a type of women's clothing that consists of a large, stiff petticoat made of fabric or netting. The skirt is supported by a metal or wooden hoop, which gives the skirt its shape and volume. The hoop skirt was popular in the mid-19th century and was often worn with a corset. The NET version of the hoop skirt was popularized in the late 19th century and was made from a lightweight material such as tulle or lace.
