Young Brunette Girl With The Pink Corselette

Merry widow
A corselet was released by Warner's in 1955, named after The Merry Widow, a 1905 operetta that has been adapted several times into feature-length films. This new design featured demi-cups and a shorter girdle than its predecessors. This type of lingerie is also known as a torsolette, and is used in bridal lingerie, much like the bustier.
The original merry widow was a corselet incorporating slim panels of black, elastic yarn netting. A heavy-duty zipper was inserted behind a velvet-backed hook-and-eye flange, and the entire garment was lined with nylon voile. Nine long, spiral wires were encased in black satin.
