A bandeau is a basically a "band" of cloth. Through history bandeaus have been worn may places but right now if you hear a woman talking about a bandeau she is referring to a bandeau that you wear around you chest, frequently worn with strapless or open backed tops/dresses where their normal everyday bra isn't going to work because the straps/cups or other portions of the bra would show. The bandeau is generally worn so you can see parts or bits of the bandeau such as the one we have pictured here.
