Catsuit

Catsuits are close-fitting one-piece garments that cover the torso and the legs, and often the arms. They are often made with leather, chiffon, latex or spandex materials. The suits usually close with zippers in the front or back.
Catsuits were worn as early as the 1940s. They can be worn by males or females. Despite their name, they do not have feline characteristics.
Catsuits may also be transparent or completely opaque.
Some people consider catsuits to be fetish items.
