10DD Bra Size Collection
Understanding 10DD: A Confident Fit
Finding your best bra fit can completely transform how you feel—especially when you’re a 10DD. This size combines a snug band (around 70cm) with a fuller bust, making it ideal for curvy women seeking comfort and shape.
In Australian sizing, "10" is your band size and "DD" reflects a bust 18–20cm larger. It's a balance that suits fit women who value both style and solid support.
From supportive basics to elegant lace, our range includes sports bras, nursing bras, and seamless everyday options tailored for you.

How to Measure Your Bra Size (Tape Measure Guide)
Finding your perfect size at home is simple:
-
Band Size (Underbust)
-
Wrap a tape measure snugly around your ribcage, just under your bust.
-
The number you get should sit close to 70cm for a size 10 band.
-
Bust Size (Overbust)
-
Measure around the fullest part of your bust.
-
Subtract the underbust number from this bust measurement.
-
A difference of 18–20cm? You're likely a DD cup.
If you’re between sizes, check out your sister size—like 8E or 12D—to find the perfect fit with slight tweaks in band width.
Sister Sizes and Alternatives
Your cup volume stays the same, even if the band changes—this is where sister sizes come in. They help you achieve a better fit when your usual size feels too snug or too loose, or when your preferred style isn't available in your exact size:
These variations in sizes are ideal for different body shapes and preferences.
