Step 1: Find your band size
| Underbust (in) | Underbust (cm) | US / UK band | EU band |
|---|---|---|---|
| 29 - 30 | 73.5 - 76 | 30 | 65 |
| 31 - 32 | 78.5 - 81 | 32 | 70 |
| 33 - 34 | 84 - 86.5 | 34 | 75 |
| 35 - 36 | 89 - 91.5 | 36 | 80 |
| 37 - 38 | 94 - 96.5 | 38 | 85 |
| 39 - 40 | 99 - 101.5 | 40 | 90 |
| 41 - 42 | 104 - 106.5 | 42 | 95 |
| 43 - 44 | 109 - 112 | 44 | 100 |
If your underbust measurement is an odd number, round up to the next even number.
Step 2: Find your cup size
| Bust minus band (in) | Approx. (cm) | US cup | EU cup |
|---|---|---|---|
| 1 | 2.5 | A | A |
| 2 | 5 | B | B |
| 3 | 7.5 | C | C |
| 4 | 10 | D | D |
| 5 | 12.5 | DD | E |
| 6 | 15 | DDD | F |
| 7 | 17.5 | G | G |
Example: An underbust of 33 in rounds up to a 34 band. A bust of 37 in minus 34 is a 3 in difference, which is a C cup. Your size is 34C (EU 75C).
Sister sizes
Sister sizes have the same cup volume on a different band. If the band fits but the cups don't, or the other way around, try a sister size.
| Band tighter | Your size | Band looser |
|---|---|---|
| 32C | 34B | 36A |
| 32D | 34C | 36B |
| 34D | 36C | 38B |
| 36D | 38C | 40B |
| 38D | 40C | 42B |
This is a general guide. When a product page lists its own measurements, use those first, since fit can vary by style and fabric.
