Your underwear can make or break an outfit, so it’s important to know what fits your shape. Getting the fit of your bra right is crucial. Follow our step-by-step guide* to getting it right (and don’t forget the measuring tape!)
*This method is most effective on smaller cup sizes (A-C).
Place the measuring tape just under your bust and around your ribcage, making sure it sits at the same height on the back as on the front. This will give you your band size.
| Band measurement | ||
|---|---|---|
| CM | IN | Band Size |
| 63-65 | 25-26 | 30 |
| 68-70 | 27-28 | 32 |
| 73-75 | 29-30 | 34 |
| 78-80 | 31-32 | 36 |
| 83-85 | 33-34 | 38 |
| 88-90 | 35-36 | 40 |
Making sure the tape is level on your front and back, hold it around the fullest part of your bust. Remember not to hold too tight.
Substract your band measurement from your cup measurement and then find the resulting number in the table below to find out what cup size you should be wearing.
| Band - Cup = | ||
|---|---|---|
| CM | IN | Cup Size |
| 10 | 4 | A |
| 13 | 5 | B |
| 15 | 6 | C |
| 18 | 7 | D |
| 20 | 8 | DD |
| 23 | 9 | E |
| 25 | 10 | F |
Example:
Step 1: Band measurement=80cm (Band size=36)
Step 2: Cup measurement=60cm
Step 3: Band measurement - Cup measurement (80-60cm)=20cm
Your cup size=DD
Your bra size = 36DD
