What is a bustier

A bustier is an article of clothing for women, which is form-fitting and is traditionally worn as lingerie. It looks somewhat like a Basque, but a bustier is shorter. It reaches down only to the ribs or the waist and has a different function: its primary purpose is to push up the bust by tightening against the upper midriff and forcing the breasts to move up, while gently shaping the waist. These days, it is often made with mesh panels rather than boning.
