It is a similar style of garment to a one-piece swimsuit or bodysuit, but is typically looser and sheerer. A one-piece undergarment which combined a camisole and knickers appeared in the 1910s under the name envelope chemise or camiknickers. It was considered an appropriate garment to wear under the shorter dresses which came into fashion in the 1920s.

The style gained popularity during World War II when women who served in military-related duties wore trousers instead of skirts. By the late 1940s, the garment lost its popularity. A version reappeared as a lingerie garment in the late 1960s, featuring a bra top and attached slip, to wear under short, shift dresses, and replace half slips. Often the bra top was an underwire style, and the entire garment was sized by the bra. It was called both a “teddy” or “braslip”, usually in traditional lingerie colors, and young women especially liked them.
