What is a plunge bra?
A plunge bra has a deep centre front and angled cups, making it ideal for low-cut tops or dresses. It creates cleavage without adding bulk and is designed to stay hidden under plunging necklines.
Can you wear plunge bras every day?
Yes! Many plunge bras are designed for daily comfort and support. They can give a flattering shape under most outfits—not just for special occasions.
Are plunge bras suitable for bigger busts?
Absolutely. We stock plunge bras for D cups and up, with side support panels and wider straps to keep you lifted and comfortable. Brands like PrimaDonna and Panache cater beautifully to fuller figures.
What’s the difference between a plunge bra and a push-up bra?
Plunge bras focus on shape and neckline, while push-up bras add padding to enhance cleavage. Some plunge styles have light padding, but they’re more about contouring than boosting volume.
Can I get fitted for a plunge bra at The Foundation?
