Young Brunette Girl Reveals In Stockings Near The Window At Home

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.
In 1912, the US had its first professional underwear designer. Lindsay "Layneau" Boudreaux, a French immigrant, established the short-lived panty company Layneau. Though her company closed within one year, it had a significant impact on many levels. Boudreaux showed the world that an American woman could establish and run a company, and she also caused a revolution in the underwear industry. Boudreaux is possibly the reason why upscale underwear and panty stores exist today.
In 1913, a New York socialite named Mary Phelps Jacob changed women's fashion forever when she created the first brassiere by tying two handkerchiefs together with ribbon. Jacob's original intention was to cover the whalebone sticking out of her corset, which was visible through her sheer dress. Jacob began making brassieres for her family and friends, and news of the garment soon spread by word of mouth. By 1914, Jacob had a patent for her design and was marketing it throughout the US. Although women had worn brassiere-like garments in years past, Jacob's was the first to be successfully marketed and widely adopted.
