Pantyhose (also called tights) are sheer, close fitting coverings of the body from the waist to the feet, most frequently worn by women. Like stockings they are usually made of nylon. The one-piece pantyhose garment appeared in the 1960s and provided a convenient alternative to stockings (nylons).
In the United Kingdom, Ireland and some fellow Commonwealth nations knickers is a word for women’s undergarments.
