10C Bra Size – Find Your Perfect Fit
Understanding the 10C Bra Size
A 10C bra size is part of the Australian sizing system. It combines a smaller band size with a moderate cup volume. In this context:
- Band size: The '10' represents the band, which fits an underbust (ribcage) measurement of approximately 68–72 cm.
- Cup size: The 'C' cup corresponds to a bust measurement roughly 14–16 cm greater than your underbust, reflecting your cup volume.
This size is ideal for petite frames—typically those with a narrow underbust of 68–72 cm and a modest bust projection—seeking structured support and comfort without excess padding. At The Foundation, we offer a curated range of 10C bras to meet these needs with expert precision—each style selected to support and flatter this specific size for everyday confidence and comfort.

How to Measure Your Bra Size with a Tape Measure
Proper bra fitting is essential. Here’s how to find your true bra size using just a tape measure:
Measure your band size:
Wrap the tape snugly around your ribcage, just under the bust.
Keep the tape measure parallel to the ground.
Round to the nearest whole number. 68–72 cm = AU size 10 band.
Measure your bust size:
Measure around the fullest part of your bust.
This gives you your bust measurement or overbust size.
Calculate your cup size:
Subtract your band size from your bust size.
A difference of 14–16 cm equals a C cup in the Australian size system.
Refer to our full size guide and size charts for even more clarity on body measurements.
Sister Sizes for 10C
Can’t find your perfect size in 10C? Try these sister sizes or alternate sizes:
