Young Brunette Girl With The Pink Corselette

A corselet or corselette is a type of foundation garment, sharing elements of both brassieres and girdles. It may incorporate lace in front or in back. The term originated by the addition of the diminutive suffix "-ette" to the word corset.
History
The corselet was originally a piece of armor, covering the torso; the origin of the English word comes from cors, an Old French word meaning "bodice". The corselet as an item of women's clothing began to gain traction in 1914, as a substitute for wearing two separate pieces (a brassiere with either a girdle or a corset). The bust uplift cups were first introduced in 1933, but did not become common until 1943.
