6HH Bras – Supportive Styles for Petite Frames & Full Busts
For those with a petite rib cage and a full bust, the 6HH bra size offers tailored support and precision in fit. At The Foundation, we specialise in hard-to-find sizes like 6HH, ensuring your band size hugs firmly without digging in — while the cup size fully supports and encases your breast tissue. Each piece is chosen for its comfort, lift, and flattering silhouette.
What Is a 6HH Bra?
6HH is a specialty size combining a 58–62 cm band measurement with a cup size 12 cm+ larger than the band. It’s perfect for curvy women and fit women who need serious support without compromising on elegance or comfort. Whether you're updating your current bra size or shopping for your first precision fit, this size ensures security for fuller busts.

How to Measure for 6HH
Use a measuring tape and follow these steps:
- Step 1 – Band size: Wrap the tape snugly around your under bust. This should fall between 58–62 cm for size 6.
- Step 2 – Bust size: Measure around the fullest part of your bust, tape parallel to the ground.
- Step 3 – Cup size: Use the difference between bust and band to identify your cup size. A 12 cm+ difference generally lands in HH territory.
