tights
Tights are a piece of hosiery similar to pantyhose. They are made of a thick material that covers from the waist to the toes. Tights are primarily used by ballerinas, dancers, and gymnasts typically worn under a leotard. They come in an array of different colors and patterns, but are much thicker than pantyhose are. They can be worn by anyone, usually in place of pantyhose for fashion reasons, or for warmth. Tights are sevenfold thicker than pantyhose, and are often worn in their place when it is cold out; or can be worn for fashion reasons due to their colors/patterns on them to coordinate with any particular outfit.
