A
catsuit is a skin-tight
one-piece garment with sleeves and long legs, and sometimes with
feet or gloves, sometimes with a hood.
Unlike a
unitard, its use rarely involves sports, and it may be made of
leather,
rubber,
PVC, or
velour
instead of
spandex.
It is identical to a
unitard in construction, but the term 'catsuit' tends to be
preferred in fancy-dress
costume or
erotic
contexts.
