Breast augmentation
The modern prosthetic breast was invented in 1961, by the American plastic surgeons Thomas Cronin and Frank Gerow, and manufactured by the Dow Corning Corporation; in due course, the first augmentation mammoplasty was performed in 1962. There are five generations of medical device technology for the breast-implant models filled with silicone gel; each generation of breast prosthesis is defined by common model-manufacturing techniques.
Training bra
Oleg Cassini made a provocative "Room at the Top Bra" in nylon and Lycra spandex for Peter Pan. In the early 1960s, bra makers marketed to girls 13–19, and later in '60s they targeted pre-teen girls age 10–12. New labels like Teenform, Teencharm, and Heaventeen catered to their market. Some companies' advertisements showed girls waist up wearing only a bra. Mercy Dobell, editor of "Corset and Underwear Review", wrote that "the bra has joined lipstick and 'heels' in becoming one of the beloved symbols of growing up. Mass media encourages teens and tweens to begin wearing lingerie at a younger age, before or as soon as their breasts begin to develop, as a way to advertise their sexuality.
