10A Bra Size Collection | The Foundation
Understanding the 10A Bra Size
The 10A bra size is beautifully suited to those with a petite body size and a more delicate bust shape, offering just the right balance of support and comfort. In Australian sizing, the "10" represents your band size, which equates to a snug underbust band measurement of approximately 68–72 cm. The "A" cup size indicates a bust measurement roughly 10 cm larger than your underbust. So, if your underbust is around 70 cm, your bust measurement would typically measure about 80 cm.
This size is a perfect match for women who need support and shape without bulk. It's ideal for younger wearers, those with smaller busts, or anyone seeking minimalist, comfy coverage. It’s also helpful to understand your clothing size in relation to lingerie, so you can find a well-fitted style every time.

How to Measure Your Bra Size
All you need is a soft measuring tape and a few minutes in front of the mirror!
- Measure your band size (underbust): Wrap the tape snugly around your ribcage, just under your bust. Make sure the tape measure stays parallel, level, and firmly in position.
- Measure your bust size: Wrap the tape around the fullest part of your bust, again keeping the tape level and not too tight.
- Calculate your cup size: Subtract your band measurement from your bust measurement. Each 2.5cm difference equals one cup size. A 10 cm difference = an A cup.
This simple bra sizing method ensures you're always shopping in your correct bra size. Visit our fitting guide or drop into a store for a personalised bra fitting.
