A Size 12J Bra That Doesn’t Make You Work for It

If you’ve ever noticed red shoulder marks by lunchtime or felt your straps pulling uncomfortably, you know how tricky it can be to find a good 12J bra. You’re carrying a bit more than most, and with a smaller band, that weight doesn’t have many options. Most bras either squeeze you tightly or leave you bouncing around, and we get how frustrating that is. That’s exactly why Rose & Thorne 12J bras are made to give you real support without the usual discomfort. So you can move freely, breathe easily, and still feel confident and stylish.


12J Bra’s With Style and Support As Standard

Feel the difference of our Premium Support bras, made for heavier busts with a forward-lifting wire and deeper, high-cut cups that keep everything secure. For soft support, try our wirefree bras, which still offer shape and lift. Want to upgrade your workout wardrobe? Our active sports bras are the secret weapon to more comfortable movement. Want a little luxury? You can have that too, with our stunning lace bras in neutral nude and bold blue hues, plus everything in between. You can even find womens briefs and matching lingerie sets to complete the look.


What to Look for in Size 12J 

The best 12J bras feature a wide, supportive band that stays comfortably in place without digging in, cups with natural projection (not just shallow padding), and shaping that keeps everything neatly contained at the sides. If you’re feeling unsure about your size, feel free to explore our Bra Fit Tools or schedule a friendly online fitting session with one of our expert bra gurus. Then get inspired by our new arrivals and start your order!
