There are two factors related to measuring the correct brassiere size needed
The math of breast enlargement surgery
In the 1950s, a French surgeon measured a lot of breasts and came up with some important breast size relationships.
For breasts with band sizes between:
32-34 inches – each cup size = 100 gm /100cc
36-38 inches – = 200gm / 200cc
40-42 inches – = 300gm / 300cc
44-46 inches – = 400gm / 400cc
Breast enlargement with implants
If you are trying to find out what size breast implants to have placed for your breast enlargement surgery, the size-volume chart can be a starting point, though in my experience you need to multply the volume numbers above by 1.5. So, if you have a 32 band size and an A cup and want to go to a C cup, you need a minimum of 300 cc. If you are a 42B and want to go to a D cup, you need (B to D is 2 cup sizes = 300 x 1.5 =) 450 cc implants.
Brassiere sizes and breast cup size
There is an inverse relationship between bra size and cup size. For example, a 36C bra is equivalent to a 34D, a 32DD, a 38B or a 40A! As for which bra you wear, it just depends on which manufacturer you use and how comfy you feel in each bra.
I know, its confusing, but your cosmetic plastic surgeon should be able to help you choose the right size implants using a combination of math and art.
