Plunge bras for necklines that dip
Our plunge bras are low-cut bras for necklines that dip, made with at least 90% organic cotton, at least 70% recycled nylon or TENCEL™ Lyocell (95%), and nearly every style comes in XXS to XL. They are the ones to reach for under a deep V, a wrap dress or an open shirt: the cups sit low at the front and meet at a narrow, low center, so the bra frames the neckline instead of cutting across it.
What is a plunge bra?
A plunge bra is a low-cut bra with angled cups and a center that sits lower on the chest than a standard bra, which lets it sit under a low neckline where a regular bra would show. Many of the plunge bras here are non-padded, so they give shape with light structure rather than extra lift, and some are wireless, with a soft band and light support. Others take a triangle or scoop shape: if you like the lighter feel, our triangle bras and our scoop-shaped bras give the same easy feel in a different silhouette, and a few of these plunge styles double as active bras for lighter workouts.
What are our plunge bras made of?
Our cotton plunge bras are made with at least 90% organic cotton and a little elastane for stretch. Every product page lists the exact fabric composition, and you can learn more about our fabric philosophy on our materials page.
Finding your size
Fit matters more on a plunge bra than on most bras, because the low center has to sit flat against your chest for the cut to work. Start from your usual size, then check the size guide on the style you like. Many styles also go up to XXL, some to XXXL, and some come in band and cup sizes. A band that rides up usually wants a smaller band size rather than tighter straps.
Caring for your plunge bras
It is the elastic that keeps a plunge bra sitting low, so look after it: machine wash cold, in a mesh bag if you have one, skip the tumble dryer and let the bra dry flat.
