A bra with a V-shaped (plunging) neckline, angled cups, and a narrow center gore that creates the appearance of enhanced cleavage. Plunge styles should have good coverage but still work well for low-cut tops. The difference between a plunge bra and a push-up bra is that a push-up bra achieves lift through additional padding in the cup, while a plunge bra’s cups are cut to reveal more of the breast to show off your natural cleavage without sacrificing the lift, shape, and support of the bra.
