20DD Sports Bras

Supportive Sports Bras In Size 20DD

A good quality 20DD sports bra shouldn’t be impossible to find. You’re not asking for anything unreasonable, just a sports bra that fits your band size, holds your breasts in place, and doesn’t require a wrestling match to get in and out of. But if you’ve looked for size 20DD sports bras in mainstream stores before, you know most brands just try to squeeze you into a generic XL sports bra, or don’t cater for you at all. At Rose & Thorne Lingerie, we take a different approach. 

Australian Sports Bras Made for Movement

Our Australian plus size sports bras are designed with full-coverage cups, breathable stretch fabrics, and a wide underband that anchors your chest without cutting you in half. Featuring soft internal lining to reduce rubbing, a natural shape with firm hold, and a fit that can handle whatever the day throws at you, whether that’s a gym class, jog, or just chasing the kids. With a range of styles and colours to suit every situation, you’re sure to find the perfect fit for your fitness journey. 

What to Look for in a 20DD Sports Bra

At this size, a good sports bra needs balance. Firm enough to hold up to movement, but flexible enough to remain comfortable. Look for good cup depth, robust side support, and size-appropriate straps that don’t slip or dig. If you’re not 100% sure whether 20DD is still your correct size, start with our online bra fitting which takes the guesswork out of shopping online. And of course, once you’re confident about your size, you can also shop a huge range of lace and contour bras, as well as plus size underwear in sizes S to XXXL.
