Corselet

In women's clothing, a corselet or corselette is a type of foundation garment, sharing elements of both bras and girdles.

The corselet as an item of women's clothing began to gain popularity in 1914, as a substitute for wearing two separate pieces (a bra with either a girdle or a corset).

[3] "Merry widow" remains a common generic term for a corsetry-type garment in the United States, or a "basque" in the UK.

The original merry widow was a corselet incorporating slim panels of black, elastic yarn netting.

[citation needed] In biology, the term refers to the thorax of an insect, or a protective band of enlarged scales in the shoulder region of a fish.
