8 Best Plunge Bras for Your Racy Low-Cut Necklines!

Plunge Bras

Plunge bras are cut low in the center so you can wear low-cut necklines without your bra showing. However, they aren’t ‘push-up’ bras, so try not to mix them up when you’re shopping. Some plunge bras are also push-ups, and some are also minimizer bras for large breasts.

What’s the difference between plunge & push-up bras?

The real difference between plunge bras and push-up bras is that the plunge doesn’t push your breasts together to create cleavage. Push-ups, on the other hand are designed with cups that gently shape the breasts towards the center.

What this means in practice is that a plunge bra will give you a smooth contour under low-cut clothes, but won’t show a lot of cleavage. But a ‘push-up’ bra is designed to show cleavage and your breasts emerging from your bra, so it’s not meant to be worn under high necked clothing.
