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.
Corselet
The corselet as an item of women's clothing began to gain traction in 1914, as a substitute for wearing two separate pieces (a bra with either a girdle or a corset). The bust uplift cups were first introduced in 1933, but did not become common until 1943.
A corselet was released by Warner's in 1952, named after "The Merry Widow", a 1905 operetta which has been adapted several times into feature-length films. "Merry widow" remains a common generic term for a corsetry type garment in the United States, or a "basque" in the UK. It is usually strapless, and stopping on the hips, rather than extending below the hip line, like the typical corselet.. A merry widow type garment is normally fastened by hooks and eyes at the rear, and because it is strapless, it need to be well boned to prevent it from rolling over, the boning helping to support the demi-cup section. A merry widow / basque would also incorporate suspenders/garters for attaching to stockings. This type of lingerie is also known as a torsolette, and is used in bridal lingerie, much like the bustier.
