18C Bras

18 C Sizes Need Support In All The Right Places

If you wear an 18C bra size, chances are you’ve had your fair share of disappointment. Cups that gape. Bands that roll. Straps that dig. The stuff that makes you want to take your bra off by lunchtime. We’ve designed our 18C bras to do the opposite - no pinching, no slipping, no “close enough” sizing. Just comfortable, reliable support that holds everything in place without making you feel strapped in. Whether you prefer a natural shape or more enhanced shape look, you’ll find your new favourite bra with Rose & Thorne. 

Bras That Actually Fit a Size 18C Body

A bra size 18C isn’t just a C cup with a longer band, it’s a whole different fit. That’s why our 18C bras have all the features that matter - wide underband for better hold, smoothing sides to stop spillover, and soft, strong straps that don’t cut in. Whether you’re sitting at a desk, running after the kids, or out for the night, these bras can keep up. Shop your size with great savings in our bras on sale collection.
