Corset

This character wears a corset.

A corset is a garment worn to hold and shape the torso into a desired shape for aesthetic or medical purposes (either for the duration of wearing this item, or with a more lasting effect).

In recent years, the term "corset" has also been borrowed by the fashion industry to refer to tops which, to varying degrees, mimic the look of traditional corsets without actually acting as one. While these modern corsets and corset tops often feature lacing and/or boning and generally mimic a historical style of corsets, they have very little if any effect on the shape of the wearer's body.
