Young Brunette Girl Reveals Her Pantyhose And Thongs On The Mattress On The Floor

In American English the term "tights" refers to pantyhose made from thicker material, or alternately 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.
History
In the 1920s, the fashionable hemline for women rose enough to show the legs, and sheer hosiery that covered the legs was only available as stockings. They were first made of silk or rayon (then known as "artificial silk"), and after 1940 with nylon, which had been invented by Du Pont in 1938. During the 1940s and 1950s, play and film producers were having stockings sewn to the briefs of their actresses and dancers. This fact has been stated by actress-dancer Ann Miller. These garments were seen in popular motion pictures such as Daddy Long Legs.
