10D Bra Size Collection
Your Perfect Fit Starts Here: Discover the 10D Difference
If you're shopping for a 10D bra, you're in the right place. With decades of experience in personalised fittings and a reputation for precision, The Foundation is trusted by women across Australia for expertly curated lingerie that fits like a dream. At The Foundation, we understand that finding the correct bra size is more than just numbers on a tag—it’s about feeling comfortable, supported, and confident. Whether you’re new to this cup size or looking for your new favourite pieces, we’re here to guide you every step of the way.
What Does 10D Mean?
The "10" refers to your band size, which measures the circumference of your ribcage, just under the bust. A size 10 band is ideal for those with a petite frame. The "D" indicates cup volume, which reflects how much breast tissue the bra is designed to support.
So, 10D means:
- A small band size (firm fit around the torso)
- A fuller bust (D cup size volume)
This combination is typical among women with a narrow body frame and naturally full bust, though of course, every body is unique and beautiful—fit should always be based on how you feel in your bra, not just the numbers.

How to Measure Your Bra Size
Follow this simple method using a tape measure:
-
Measure your band size: Wrap the tape around your ribcage, just under your bust. Keep the tape measure parallel to the ground. Round down to the nearest whole number to find your actual band size.
-
Measure your bust: Loosely wrap the tape around the fullest part of your bust.
-
Bust measurement - Band measurement = Cup size:
-
A difference of 4 inches = D cup volume

Understanding Sister Sizing
Not all bras fit the same, even within the same size. That’s where sister sizing comes in handy. Sister sizes for a 10D bra size include:
Trying a sister size can help you fine-tune your comfort, especially if your current band size feels tight or rides up.

Clothing Sizes vs Bra Sizes
Keep in mind that clothing sizes don't always align with bra sizing. That's why we recommend using our bra size systems and fitting matrix rather than assuming your bra size based on your top size. Your underwear size systems can vary, so it's worth checking your hip measurements and bust measurement too.
