What is the point of a plunge bra?

The defining feature of a plunge bra is the deep V-shaped neckline created by the low center gore that extends down between the breasts, often to the bottom of the band. This allows the bra to stay hidden under tops and dresses with very low necklines.

Plunge bras are available in both underwire and wire-free styles. The underwire provides additional lift and shaping, while wire-free options focus more on comfort. Many plunge bras also have convertible straps that can be worn in multiple ways, such as crisscross or halter, or removable straps to wear under strapless styles.
