18C Bras

Because 18C Shouldn’t Be a Compromise

Wearing a size 18C bra shouldn’t mean putting up with gaping cups, digging straps, or bands that won’t stay put. You’ve got enough on your plate without your bra letting you down by midday. Our 18C bras are made to fit properly. No pinching, no slipping, and no vague “close enough” sizing. Just steady, all-day support that feels good from the moment you put it on.  Whether you prefer a natural shape or more enhanced shape look, you’ll find your new favourite bra with Rose & Thorne. 

Make an 18C Bra Size Work For You

An 18C isn’t just a C cup with a longer band. It’s a shape and fit all its own, and our bras are designed with that in mind. Expect wider underbands for hold, smoothing sides that stay in place, and soft but strong straps that sit comfortably all day. Whether you’re at your desk, chasingthe  kids, or heading out for dinner, these bras move with you. Shop your size with great savings in our lingerie on sale collection.

What To Look For In An 18C Bra

If you’re shopping for 18C bras, you want to balance support with style. The right 18 C bra will give you shaping through the sides and underband, not just the cups, so you can feel secure without any squish. Whether you’re searching for the perfect 18C lace bra, a wirefree option, or one of our best-selling sports bras, you’re sure to discover your new favourite with Rose & Thorne.
