A bustier (alternately bustiere) is a form-fitting garment for women, which is traditionally worn as lingerie.
Its primary purpose is to push up the bust by tightening against the upper midriff and forcing the breasts up, while gently shaping the waist. Nowadays, it might also be worn as a push-up bra under a low-backed dress, or as a camisole for outer wear. The bustier can also be worn as a half-slip under sheer upper garments if a bold display of the midriff is not desired.
A bustier resembles a basque, but is shorter. It reaches down only to the ribs or waist.
Modern bustiers are often made with mesh panels rather than the traditional boning.
