Catsuits may refer to tight-fitting body suits, basically made from latex material. They may also be in leather or pvc form. These are usually wore by women as a fetish purpose or fashion. Men can be strongly attracted to these.
Denise Richards in the movie "Undercover Brother", which was released in 2002, plays her role as a character in a tight, white, leather catsuit.
