In 1913, a New York socialite named Mary Phelps Jacob changed women's fashion forever when she cobbled the first brassiere together 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 word of mouth soon spread about the garment. By 1914, Jacob had a patent for her design and was marketing it throughout the World. Although women had worn brassiere-like garments years past, Jacob's was the first to be successfully marketed and widely adopted.

A demi or shelf bra covers only the lower half of the breast and is used to give a lift to the breasts, but does not create cleavage! Great for low neckline clothes.

Corsets are women's lingerie that are boned and close fitting. The most common use of a corset is to slim the body and make it conform to a fashionable silhouette. For women this most frequently emphasizes a curvy figure, by reducing the waist, and thereby exaggerating the bust and hips. Corsets begin either above or just below the bust and extends down to the waist or below the hips.

Hosiery, pantyhose or stockings are close-fitting, elastic garments that cover the feet and legs. Hosiery comes in various styles including silk, nylon, and fishnet.

Women's panties have their origins in the 1920's when bloomers (long underwear) became shorter and looser as the flapper look came into fashion.  The panties of this time were called step-ins.
