Pantyhose may be composed of other materials such as silk, cotton, or wool.
Mostly considered to be a garment for women and girls, pantyhose appeared in the 1960s as a convenient alternative to stockings and/or control panties (which, in turn, replaced girdles).
Like stockings or knee highs, pantyhose are usually made of nylon, or of other fibers blended with nylon.
Often sheer-to-waist pantyhose will be reinforced along and on either side of the seam in the middle of the panty.
Open-crotch pantyhose, sometimes known as crotchless pantyhose, do not have a gusset.
Opaque leg wear made of material such as spandex are often worn by both sexes for athletic activities or as utility clothing, and are usually referred to as "leggings", a term that includes casual wear.
