A plunge bra gives great cleavage under low-plunging, deep-v tops and dresses. The center of the plunge bra is cut very low, in a "V" shape. The cups of the bra push the breast in and up, giving great lift. Some plunge bras come with integrated or removable padding.

An underwire bra is a brassiere that utilizes a thin, semi-circular strip of rigid material fitted inside the brassiere fabric. The wire may be made of metal, plastic, or resin.

An unlined bra, by definition, is a bra made with one layer of fabric across the cups, no padding or foam included. The benefits of unlined bras are primarily rooted in comfort.
