12C Bras

Feel-Good Support in Size 12C

When your frame’s on the slimmer side, it doesn’t take much for a bra to feel bulky, or just… off. But when you get the fit right, it makes a world of difference. A good 12C bra gives you light lift, subtle shape, and a little extra confidence as you step out into the day. You’ll find that with Rose & Thorne. Supportive but never stiff, flattering without forcing it, these bras are made to work with your body, not against it. 

Pick Your Perfect Style in a 12C Bra

How to Find the Right Fit in a 12C Bra

For a size 12C, you want cups with just enough structure to hold their shape, a flexible band that doesn’t cut in, and straps that stay where they’re meant to. If you’re not sure it’s still your perfect size, book an online bra fitting, and one of our bra gurus can help you figure it out.
