A bandeau is the simplest bra form: a straight band of fabric across the chest, with no cups, no straps, and no underwire. It provides minimal support and is worn mainly as a layer under sheer tops, under off-shoulder garments, or as swimwear.
Historically, the bandeau emerged in the 1920s flapper era as a means of flattening the bust for the boyish silhouette of the period.
