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 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.

Wireless bras give support and shape without the underwire. Wireless bras are good for all bust types. They may also be called: soft-cup bras, wire-free bras, and non-wire bras.
