Brunette Girl Undresses Her Black Underwear On The Couch

The jockstrap was invented in 1874 by C.F. Bennett of a Chicago sporting goods company, Sharp & Smith, to provide comfort and support for bicycle jockeys riding the cobblestone streets of Boston, Massachusetts. In 1897 Bennett's newly formed Bike Web Company patented and began mass-producing the Bike Jockey Strap.
• 1900s to 1920s
By the early 20th century, the mass-produced undergarment industry was booming, and competition forced producers to come up with all sorts of innovative and gimmicky designs to compete. The Hanes company emerged from this boom and quickly established itself as a top manufacturer of union suits, which were common until the 1930s. Textile technology continued to improve, and the time to make a single union suit dropped from days to minutes.
Meanwhile, designers of women's undergarments relaxed the corset. The invention of new, flexible but supportive materials allowed whalebone and steel bones to be removed. The emancipation or liberty bodice offered an alternative to constricting corsets, and in Australia and the UK the liberty bodice became a standard item for girls as well as women.
