* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.

Shop our collection of comfortable, sexy, and supportive plunge bras. Our triangle bras and bralettes are made from luxurious fabrics, and are obsessively designed to ensure maximum comfort and lift. These v neck bras are perfect for low cut dresses and tops.

Meet #1 best seller: The Sieve Triangle Bra. This is our most supportive triangle bra, made from our Belgian power micromesh which is simultaneously airy light and surprisingly strong.

The best plunge bra for lounging is our Whipped Triangle Bra - softer than whipped cream, you could literally fall asleep in our Austrian stretch modal fabric. We are certainly guilty of it.

The Cotton Triangle Bra is a super soft, stretchy, everyday bralette that offers good support and tons of comfort. Our Cotton + Elastane blend is breathable and plenty flexible so you’ll never feel restricted. Pair it with our high thigh cheeky cut underwear: our Cotton French Cut Brief 3 and 5 Packs.

If you’re feeling fancy, our most luxurious v neck plunge bra is our Glace Triangle Bra. It’s a wireless, ultra-luxe triangle bralette: comfortable for day, sexy for night, perfect for always. Most frequently purchased with our matching Glace G-String, a minimal coverage, seamless under all things thong.
