Breast implant
Since the late nineteenth century, breast implants have been used to surgically augment the size (volume), modify the shape (contour), and enhance the feel (tact) of a woman's breasts. In 1895, surgeon Vincenz Czerny effected the earliest breast implant emplacement when he used the patient's autologous adipose tissue, harvested from a benign lumbar lipoma, to repair the asymmetry of the breast from which he had removed a tumor. In 1889, surgeon Robert Gersuny experimented with paraffin injections, with disastrous results.
Cleavage (breasts)
Development of 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." Several brassiere manufacturers, among them Wonderbra and Victoria's Secret, produce push-up and other types of bras that enhance cleavage. Frederick's of Hollywood introduced a design called Hollywood Extreme Cleavage Bra that helped give the impression of a spherical cleavage like augmented breasts that was popularized by stars like Pamela Anderson.
