The band size has to be an even number. If it’s an odd number, then you round down.

How to determine the CUP SIZE using the #2 and #1 measurements:

Subtract #2 minus #1 and if the difference between the two numbers are

1” = A Cup
2” = B Cup
3” = C Cup
4” = D Cup
5” = E Cup
6” = F Cup
7” = G Cup
8” = H Cup

9” = I Cup
10” = J Cup
11” = K Cup
12” = L Cup
13” = M Cup
14” = N Cup
15” = O Cup

Measurement #3 is not used in the determination of the Bra Size, unless we notice there’s a
huge difference in #1 and #3 measurements. This is common in body builders and swimmers.
