As you know: 2.54 cm = 1 inch (http://www.convertunits.com/from/cm/to/inch)
Is it true that you need a 13 cm (5 1/8 inch) difference between underbust and bust to be an A ?
Cups
B = 13 + 2,54 (15,54 cm or 6 1/8 inch)
C= 15,54 + 2,54 (18,08 cm or 7 1/8 inch )
D= 18,08 +2,54 (20,62 cm or 8 1/8 inch)
DD= 20,62 + 2,54 (23,16 cm or 9 1/8 inch )
What do you think ??
