Breastband, also known as a chest band or a brassiere, is an important part of a woman's bra. But did you know that there are several synonyms for the word breastband? These include brassiere, bandeau, bustier, corset, bralette and camisole. A brassiere is the most common word used for a woman's undergarment that covers the breasts. A bandeau, on the other hand, is a strapless bra that offers less support. A bustier is a full-torso garment that has a bra built into it. In contrast, a corset is a tightly-laced undergarment that shapes the torso. Bralettes and camisoles are types of bras that are usually worn as outerwear. Whatever synonym you use, the breastband is an essential garment for every woman.
