Young Teen College Girl Without Brassiere

Like other clothing, brassieres were initially sewn by small production companies and supplied to various retailers. The term “cup” was not used to describe bras until 1916, and manufacturers relied on stretchable cups to accommodate different sized breasts. Women with larger or pendulous breasts had the choice of long-line bras, built-up backs, wedge-shaped inserts between the cups, wider straps, power Lastex, firm bands under the cup, and even light boning.
In October 1932, the S.H. Camp and Company correlated the size and pendulousness of a woman's breasts to letters of the alphabet, A through D. Camp's advertising featured letter-labeled profiles of breasts in the February 1933 issue of Corset and Underwear Review. In 1937, Warner began to feature cup sizing in its products. Adjustable bands were introduced using multiple eye and hook positions in the 1930s.
Since then, bras have replaced corsets and bra manufacture and sale has become a multi-billion-dollar industry. Over time, the emphasis on bras has largely shifted from functionality to fashion.
There is an urban legend that the brassiere was invented by a man named Otto Titzling ("tit sling") who lost a lawsuit with Phillip de Brassiere ("fill up the brassiere"). This originated with the 1971 book Bust-Up: The Uplifting Tale of Otto Titzling and the Development of the Bra and was propagated in a comedic song from the movie Beaches.
