Step1. Calculate band size
Example:
25.6 Inches will round off to
26 Band size – 26 + 4 = 30
The tape should be leveled and snug.
Round the number obtained, to the nearest wholenumber.
If the number is even, add 4inches. If it’s odd, add 5.
The sum of this calculation
is your band size
Step2. Calculate bust size/ cup size
Ex: Bust = 37 inches, Band = 34 inches,
37 – 34 = 3 inches. That’s a 34C!
Wrap the tape around the fullest part of your bust
Make sure it’s not too tight or too loose and without any falls or twists.
Round off the number to the nearest whole number.
Now, subtract the band size calculated earlier from the bust measurement.
If the difference between band and bust measurement is 1, then your cup size is A. If the difference is 2, then the cup size will be B, so on & so forth.
How to select the cup size
If the difference between band and bust measurement is 1,
then your cup size is A and so on as shown below:
| Bust Band | Cup |
| Same Size | AA |
| 1′ difference | A |
| 2′ difference | B |
| 3′ difference | C |
| 4′ difference | D |
| Bust Band | Cup |
| Same Size | AA |
| 1′ difference | A |
| 2′ difference | B |
| 3′ difference | C |
| 4′ difference | D |
