Creature suits are realistic costumes used to disguise a performer as an animal, monster, or other being. They are used in film, television, or as costumed characters in live events. Unlike mascots, they are often made with a high degree of realism. In contrast with prosthetic makeup, which is applied to an actor's skin, the wearer is not normally visible outside their movements controlling the costume, although in some cases, part of the wearer's body is still visible (such as in the case of mermaids or other half-human monsters).
