8GG Bra Size – Find Your Perfect Fit
Understanding Bra Size 8GG
The 8GG bra size is a specialised fit that pairs a smaller band with a fuller bust. In Australian sizing, the "8" refers to your band size, usually fitting an underbust measurement of 68–72cm. The "GG" cup denotes a very full bust, offering ample support and coverage without sacrificing everyday comfort. This size is especially well-suited for curvy women looking for bras that prioritise shape, support and style.

How to Measure Using a Tape Measure
Here’s how to measure accurately with a tape measure:
- Band Size: Wrap the tape firmly around your ribcage, just under the bust. If the measurement is between 68–72cm, your band size is likely an AU 8.
- Bust Measurement: Measure around the fullest part of your bust, keeping the tape comfortably snug but not tight.
- Cup Size: Subtract your band size from your bust measurement. A difference of around 22–24cm typically corresponds to a GG cup.
