Shop Size 20G Bras – Premium Support for a Perfect Fit
What Makes a 20G Bra Size Unique and Supportive?
Shopping for a size 20G bra that offers expert support and all-day confidence? You’re in the right place. A 20G bra in Australian sizing offers a band size of 20 with a G cup volume, catering to those with a smaller torso and a fuller bust. This specialist size is ideal for those who need serious support from the start—think multi-piece cups, large side support panels, and supportive underwire designs. At The Foundation, every piece in our collection is expertly selected with your comfort in mind.

How to Measure with a Tape Measure for the Right Fit
Use our Bra Fit Guide—an easy-to-follow online resource with visual instructions—for quick at-home measuring:
- Band Size: Wrap a tape measure firmly around your ribcage under the bust. Round to the nearest even number.
- Bust Measurement: Measure around the fullest part of your bust with the tape straight and level.
- Bra Sizing: Subtract your band size from your bust measurement. Each 2.5 cm difference equals one cup size.
You can also book a Bra Fitting in-store or try our virtual bra fitting services from the comfort of your home.
