Brunette Girl Undresses Her Black Underwear On The Couch

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.
Men's underwear was also on the rise. Benjamin Joseph Clark, a migrant to Louisiana from New Jersey, opened a venture capitalist firm named Bossier in Bossier Parish. One product manufactured by his firm was tightly fitting boxers that resembled modern underwear. Though the company was bankrupt by the early 1900s, it had some impact on men's underwear design.
The increase in the number of underwear manufacturers necessitated the birth of undergarment advertising. The first underwear print advertisement in the US ran in the Saturday Evening Post in 1911 and featured oil paintings by J.C. Leyendecker of the "Kenosha Klosed Krotch". Early underwear advertisements placed emphasis on durability and comfort; fashion was never a selling point.
By the end of the 1910s, Chalmers Knitting Company split the union suit into upper and lower sections, effectively inventing the modern undershirt and drawers. Women wore lacier versions of this basic duo known as the camisole and drawers.
