Plunge Bras

A plunge bra is a bra with a deep V-shaped center that dips low between the cups, so it stays hidden under low-cut, V-neck and plunging necklines. The angled cups sit closer together to lift the bust and enhance cleavage. It's defined by its neckline shape, so you'll find plunge bras in push-up, t-shirt, strapless and full-figure versions.

Anything with a low or deep neckline — V-neck tops, wrap dresses, deep scoop necks and plunging necklines. The low center keeps the bra hidden where a regular bra would peek out. Match the depth of the bra's V to how low your top goes; a deep plunge handles the most revealing cuts.

A plunge bra has a deep, low center-V and is best under low-cut and V-neck tops. A balconette bra has partial cups and a wider, more horizontal neckline, best under square, wide and off-shoulder tops. Plunge goes deep in the center; balconette opens wide across the top.

They describe different things. A plunge is defined by its low center-V neckline; a push-up is defined by angled padding that lifts and builds cleavage. Many plunge bras are also push-up (a "push-up plunge"), combining the low center with added lift — but a plunge doesn't have to be padded.

A deep plunge bra has an even lower center cut than a standard plunge, dropping the gore further between the cups. It's designed for the most extreme low necklines — deep-V dresses and tops where an ordinary plunge would still show. The cups often connect very low or with a small center piece.

Yes — the angled cups sit closer together to lift and center the bust, which naturally enhances cleavage. A push-up plunge takes it further with padding that builds fuller cleavage, which is ideal if you want more definition under a low-cut top.

A plunge bra. Its low center-V is cut specifically so the bra stays hidden under low and V-shaped necklines, unlike a standard bra whose center gore would show. For everyday low necklines choose a smooth t-shirt plunge; for a deep-V dress, a deep plunge.

Yes. A strapless plunge combines a low center-V with a strapless design, so you can wear it under low-cut and off-shoulder or strapless tops at the same time. Look for a secure, grippy band and molded cups, since the band carries all the support without straps.

Very — a push-up plunge is one of the best ways to create the appearance of fuller cleavage on a smaller bust, since it lifts and centers what you have under a low neckline. Choose a padded or push-up plunge for the most noticeable effect.

Yes, when they're designed for full busts. Full-figure plunge bras use deeper cups, underwire and a strong band to lift and contain a fuller bust securely while keeping the low center. Look for full-figure or plus-size plunge styles for the best support. See the plus-size edit.

Absolutely. A smooth t-shirt plunge is comfortable and invisible enough for daily wear, and useful all-round since it works under low and regular necklines alike. Many people keep a t-shirt plunge as an everyday bra and a lace or push-up plunge for going out.

Because the center gore sits low, the band does most of the support work — so make sure it's snug and level, especially for fuller busts. The cups should fully contain your bust with no spillage, and the low center should lie flat against your chest without gaping. Re-check your size with the bra size chart if needed.

Hand-wash in cool water with a gentle lingerie detergent, or use a lingerie bag on a delicate cycle. Reshape any padded cups and lay flat to dry — never wring or tumble-dry, which breaks down the molded shape and elastic over time.
