the underwire bra started in the 1930s, though it did not gain widespread popularity until the 1950s, when the end of World War II freed metal for domestic use. Aviator and filmmaker Howard Hughes designed a prototype for an aerodynamic underwire bra for Jane Russell when filming The Outlaw in 1941. According to Hughes, the resultant amount was "the length of the actual cleavage is five and one-quarter inches." Bras in 1940s left a substantial amount of fabric in the center, thus creating a separation of breasts instead of the pushed-together cleavage of today. Frederick Mellinger of Frederick's of Hollywood created the first padded bra in 1947, followed by an early push-up bra a year later (dubbed "The Rising Star"). A padded bra adds material (foam, silicone, gel, air, fluid etc.) to the cups to help the breasts look fuller. There are different designs, from a slight lift to a highly pushed-up effect, that provide coverage and support, hides nipples, add shape to breasts that are far apart and adds comfort. Graduated padding uses more padding at the bottom of the cups that gradually tapers off towards the top. There also are semi-padded bras that suits deep neck dresses. With the advent of padded bras, sales of removable pads took a plunge, though some padded bras also have removable inserts. Actress Julia Roberts was required to wear a custom made silicone gel filled bra for the movie Erin Brockovich in order to increase her cleavage. Brassières were initially manufactured by small production companies and supplied to retailers. The term "cup" was not used until 1916, and manufacturers relied on stretchable cups to accommodate different sized breasts. Women with larger or sagging breasts had the choice of long-line bras, built-up backs, wedge-shaped inserts between the cups, wider straps, Lastex, firm bands under the cup, and light boning. In October 1932, the S.H. Camp and Company correlated the size and pendulousness of breasts to letters 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 hook and eye closures in the 1930s. By the time World War II ended, most fashion-conscious women in Europe and North America were wearing brassière, and women in Asia, Africa, and Latin America began to adopt it. 1960s–1980s In fall
