Meet The Most Supportive Size 18 Bras
If you wear a size 18 band, you’ve already felt the frustration of finding a bra that fits well. From one brand to another the sizing can fluctuate, while the shapes tend to simply be scaled up from smaller sizes. The cups sit wrong. The band digs in. It’s just an all-round awful experience until the moment you take it off at the end of the day. Rose & Thorne bras are different. Every style in our collection is designed with a size 18 frame in mind. The shape and support are well-considered, the bra itself is well-made, and honestly, you may even forget you’re wearing it - it’s that comfortable.
Whether you’re after something seductive and lacy or seriously sporty, a nude or a multicoloured, you’ll find supportive size 18 bras in every style and cup size.
