Bra Size Guide
Fitting fundamentals

1. Check the bottom band
Make sure the bottom band is snug and lies flat across your back — not riding up or loose around your rib cage.

2. Then check the cups
The cups should fit smoothly — spilling out the sides or front means the cup size is too small, while extra space means the cups are too big.

3. Last thing: the straps
Straps should lie smoothly against your skin, without sliding around or digging uncomfortably into your skin.
how to measure your bra size

Get everything you need
Make sure the bottom band is snug and lies flat across your back — not riding up or loose around your rib cage.
Figure out your band size
You’ll need a flexible tape measure. It’s also best to wear a bra that doesn’t change your shape — no padding or compression. You can also just skip the bra.
Figure out your cup size
Measure around the fullest part of your boobs — which may not be the center — and round up to the nearest inch. Then subtract your rib cage measurement. The difference in inches is your suggested cup size. If you get a fraction, round up to the larger size.
