18DD Bras

18DD Bras That Do the Job Properly

At 18DD, you’re outside most brands’ “standard” range, meaning you’re expected to make do with bras that aren’t designed for fuller busts. Maybe the cups are deep enough, but the band rides up. Or the fit’s okay… until midday. Our 18DD bras are designed differently. Full coverage, extra hold, and thoughtful shaping that works with your body and against gravity. Whether you’re looking for a natural shape or a more enhanced look, you’ll find your new favourite bra with Rose & Thorne. 

Comfortable Support In An 18DD Cup

All our 18 DD bra sizes feature a wide underband with a 3-hook closure which gives a secure, comfortable fit. Our straps are a standard width, so they’re strong enough for daily wear without feeling over-engineered. You’ll also find smoothing side panels, deep full cups, and breathable fabrics. No slipping. No readjusting. Just comfort all day long. Now that’s more like it.

Find The Best 18DD Size Bra For You

When shopping for 18 DD bras, focus on full cup styles which will give shape and make the most of your volume. A bra should give you lift through the underband and side seams, not just the cups, which will help reduce the strain on your back and shoulders. Whether you're after lace, wirefree, or everyday styles, our 18DD bras will stay comfortable from morning to night.
