A catsuit is a one-piece form-fitting garment that covers the torso and the legs, and frequently the arms. They are usually made from stretchable material, such as lycra, chiffon, spandex, latex, or velour, but may use less elastic materials, such as leather or PVC. Catsuits frequently close by means of a zipper at the front or back. A catsuit is regarded as outerwear, but not normally street wear. Catsuits are also used for sexualization or other types of sexuality.
