6GG Bras – Designed for Petite Frames & Larger Cup Volume
Shopping for 6GG bras can be tricky — but at The Foundation, we've made it easy. Our collection is curated for women with a small band size and a deep cup size, offering the support, shape, and style you deserve. Whether you’re dressing for everyday wear or need structured support for fuller breast tissue, our 6GG bras are all about accurate sizing and optimal comfort.
What Is a 6GG Bra?
6GG combines a 58–62 cm under bust measurement with a large cup volume. It’s ideal for curvy women who need substantial cup size support but wear a petite band size. Many customers with asymmetrical breasts or unique breast shapes find 6GG bras to be more secure and better fitting than standard sizes.

How to Measure for 6GG
Use a soft tape measure for bust measurement and band size:
- Step 1: Wrap the tape snugly around your ribcage to find your under bust.
- Step 2: Measure across the fullest part of your bust.
- Step 3: Use the difference in inches to determine your cup size.
