- Note measurement in inches
Band Size Chart
| Underbust Measurement (inches) | Band Size |
|---|---|
| 26–27 | 28 |
| 28–29 | 30 |
| 30–31 | 32 |
| 32–33 | 34 |
| 34–35 | 36 |
| 36–37 | 38 |
Step 2: Measure Your Bust Size
How to Measure:
- Measure around the fullest part of your bust
- Keep tape straight and level
- Do not compress the bust
Note this measurement.
Step 3: Calculate Your Cup Size
Cup size = Bust measurement − Band measurement

|---|---|
| 1 inch | A |
| 2 inches | B |
| 3 inches | C |
| 4 inches | D |
| 5 inches | DD |
| 6 inches | E |

Bust: 36 inches
Band: 32 inches
Difference = 4 inches → Cup D
Final Size = 32D
