How to find your size
Bra fit comes down to two measurements: your band and your bust. Here's how to take them accurately.
1. Band measurement
Wrap a soft tape measure snugly around your ribcage, directly under your bust, keeping it horizontal. This gives your band size.
2. Bust measurement
Wrap the tape around the fullest part of your bust, keeping it level across your back, without pulling tight. This gives your bust measurement.
3. Find your cup size
Subtract your band measurement from your bust measurement. The difference in inches corresponds to your cup size:
| Difference | Cup Size |
|---|---|
| Less than 1" | AA |
| 1" | A |
| 2" | B |
| 3" | C |
| 4" | D |
| 5" | DD |
| 6" | E |
Your full size is your band number plus your cup letter — for example, 34C or 36DD.

A few fit tips
- Sizing can vary slightly between brands like Roza, Gracya, Wolbar and Control Body — check individual product descriptions for brand-specific notes.
- If you're between sizes, size up in the band and down in the cup, or vice versa, depending on how you prefer your fit.
