12FF Bra Size – Comfort, Support & Style
Find Your Perfect Fit in 12FF
Welcome to our expertly curated 12FF bra size collection – where everyday comfort, confidence, and support come together. If you wear a 12FF, you understand the importance of a bra that fits just right. Let’s break it down: the "12" refers to your band size (around the body under the bust), and "FF" is your cup size, indicating a fuller bust volume. This Australian size is designed to support a balanced fit for those with a medium band size and fuller bust, offering both lift and stability. We specialise in accurate sizing so you can feel empowered in your exact size.

How to Measure Your Bra Size
Using a tape measure, follow these simple steps to find your ideal fit:
- Band size: Wrap the tape measure snugly around your ribcage, directly under your bust. Make sure it's level all the way around. Round to the nearest even number.
- Bust size: Measure around the fullest part of your bust, keeping the tape relaxed and level.
