pantyhose

pl.n. American English

A woman's one-piece undergarment consisting of underpants and stretchable stockings.

Pantyhose are sheer close fitting coverings of the body from the waist to the feet, most frequently worn by women.

The term 'pantyhose' originated in the United States, referring to the combination of 'panties' (an American term for women's underpants) with sheer nylon hosiery. In the United Kingdom, they are called tights.
