A plunge bra gives you lift and cleavage under low-cut tops and deep-V dresses, without gaping cups or a bra that peeks out. Thirdlove designs plunge bras with a low center panel and angled, wider-set cups, so the bra disappears under dropped and wide necklines. You still get real support and a smooth, invisible look, in a fit built around your true size.
A plunge bra has a low center gore and angled, wider-set cups that form a deep-V the bra tucks under. That low-cut center is what keeps it hidden beneath revealing necklines while the cups still lift and support.
The cut sits lower between the cups than a full-coverage or t-shirt bra, so you get less coverage up top without losing support. The straps sit further out for subtle lift, and Thirdlove makes them no-slip so they stay put.
The two are defined by different things. A plunge bra is defined by its low center gore and deep neckline. A push-up bra is defined by added padding that lifts and pushes in.
Many Thirdlove plunge styles do both. Removable pads let you add push-up-style cleavage, take it out for a more natural shape, or balance asymmetry between cup sizes. If lift is your priority, our push-up bras focus on it.
Reach for a plunge bra whenever your neckline dips low. It's the go-to bra for low-cut dresses and tops, wrap styles, V-necks, and button-downs worn open.
These styles work for everyday wear and special occasions alike. You get support and lift without your bra showing, whether you're at work or out for the night.
A plunge bra should feel secure without pinching, gaping, or shifting as you move. Run these three checks to confirm your fit:
Then move around in the mirror. Your plunge bra should stay in place as you reach, bend, and twist.
Plunge bras work for just about everyone. Whether you have a petite or fuller bust, and close-set or wide-set breasts, the low-cut design and outward-set straps adapt to your shape.
Fit is where Thirdlove stands out. We make plunge bras in band sizes 30 to 44 and cups A to H, including half-cups for in-between sizes, so you can get closer to a true fit.
There's no single plunge bra for every outfit, so this collection spans wired and wireless, padded, push-up, unlined, and lace styles. Match the style to the lift you want and how you're dressing:
Wired styles give you the most lift, while wireless and unlined options lean softer for all-day comfort. Removable pads across several styles let you dial cleavage up or down.
Every Thirdlove plunge bra is built to lift and shape without spilling over or showing under low necklines, in inclusive sizes with no-slip straps and skin-friendly fabrics.

Do Plunge Bras Give Cleavage?
Yes, the angled, wider-set cups draw your breasts toward the center for natural cleavage. With Thirdlove's removable pads, you can add more or take it down for a softer shape.
How Low Does a Plunge Bra Go?
The center gore sits low between the cups, well below where a standard bra sits, so it stays hidden under deep-V and low-cut necklines. That low center is what lets your outfit take the spotlight.
Are Plunge Bras Good for Larger Busts?
Yes, underwire and adjustable no-slip straps give fuller busts real lift and support without spillage. Thirdlove makes plunge bras in band sizes 30 to 44 and cups A to H, including half cups for in-between sizes.
Can You Wear a Plunge Bra Every Day?
Absolutely, Thirdlove plunge styles are built for all-day wear with skin-friendly fabrics and no-slip straps, not just special occasions. You get comfort and support from morning to night.
What Should You Wear With a Plunge Bra?
Reach for a plunge bra with deep-V and low-cut tops and dresses, wrap styles, and button-downs worn open. The low center keeps the bra out of sight where a standard bra would show.
