20FF Bra Size Collection
What is a 20FF Bra Size and Who is it For?
The 20FF bra size combines a band size of 20—equal to a 95cm underbust in Australian sizing—with an FF cup, representing a generous cup volume designed for fuller busts. If you’re shopping for D-K cup bra-fitters, you’re in the right place. A 20FF bra is engineered for a firm fit, ideal support, and all-day comfort.
Our expertly curated collection includes wireless, seamless, strapless, and even sports bras—perfect for active lifestyles and fuller figures. Whether you’re after an everyday t-shirt bra or bikini tops with the perfect lift, our expert bra-fitting service ensures a tailored fit with every wear.

How to Measure Your Bra Size Using a Tape Measure
Finding the perfect fit starts with two simple body measurements—grab your tape measure and follow these steps:
- Band Size (Back Size): Measure snugly around your ribcage, just under your bust. Round to the nearest whole number.
- Bust Measurement: Measure around the fullest part of your bust while wearing a non-padded bra.
- Cup Letter: Subtract your band size from your bust measurement. Each inch difference equals one cup size.
