Tights are a like snug, super long socks that go all the way up to your waist. Ballet dancers wear tights — and so does Superman.
Tights are worn under skirts or dresses, by dancers and runners, and by actors playing roles including Hamlet and Peter Pan. The name comes from "tight-fitting breeches," and beginning in the early 19th century, tights referred to gear worn by acrobats and dancers. Today, the words pantyhose and stockings are commonly used interchangeably with tights.
