A unitard is a skintight, one-piece garment with long legs and sometimes long sleeves, usually stopping at the wrists and ankles. It differs from a leotard which does not have long legs. The garment can be thought of as a combination of a leotard and leggings, and was historically called a "one-piece long legged leotard". The term unitard is mostly used in relation to sports, while it is usually referred to as a catsuit in other contexts.
