Terminology
The term "pantyhose" originated in the United States to refer to the combination of panties (an American English term) with sheer nylon hosiery. In British English, these garments are called "tights", a term that refers to all such garments regardless of whether they are sheer lingerie or sturdy outerwear.
In American English the term "tights" refers to pantyhose made from thicker material, or alternatively to opaque legwear typically made of a stretchy material like spandex. Opaque tights are worn by both sexes for athletic activities or as utility clothing, and can also be referred to as "leggings", a term that also includes other garments.
