The brassiere has long been thought to be a relatively modern invention, but in 2008 archaeologists working at a castle in Austria discovered evidence of modern-style bras made from linen.[11][12] The bra, found in the Lengberg Castle, looks somewhat similar to the modern longline brassiere with the cups made from two pieces of linen sewn with fabric extending down to the bottom of the torso with a row of six eyelets for fastening with a lace or string. The brassiere also has two shoulder straps and is decorated with lace between the cleavage. Using radiocarbon dating, the Swiss Federal Institute of Technology, estimates the brassiere was from sometime between end of the 14th to the second half of the 15th century.[13] From the 16th century onwards, the undergarments of wealthier women in the Western world were dominated by the corset, which pushed the breasts upwards. In the latter part of the 19th century, clothing designers began experimenting with various alternatives to the corset, trying things like splitting the corset into multiple parts: a girdle-like restraining device for the lower torso, and devices that suspended the breasts from the shoulder for the upper torso.
Sigmund Lindauer from Stuttgart-Bad Cannstatt, Germany developed a brassiere for mass production in 1912 and patented it in 1913. It was mass produced by Mechanischen Trikotweberei Ludwig Maier und Cie. in Böblingen, Germany. With metal shortages, World War I encouraged the end of the corset. By the time the war ended, most fashion-conscious women in Europe and North America were wearing brassieres. From there the brassiere was adopted by women in Asia, Africa, and Latin America.
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.
