You can know a woman's bra size by asking her. If you do not think it is appropriate to ask her for her bra size, then her bra size is probably none of your business.
Your only option is to guess the girl's bra size. If you are not buying her a bra, you don't need to know her bra size. Try to find out something that's important to her instead.
A 75A bra size is the same as 34AA in the United States.
The different numbers before "A" in a bra size are the size of the band. A bra size 32A will fit a woman who is about 32 inches around the rib cage.
It isn't really abnormal to where a too big or too small size of a bra. It just varies to your weight. It is a little big but you can't change your bra size.
Bra size is composed of two parts, band size and cup size. Band size is a number, like 36. Cup size is a letter, like 'C'. To determine band size, measure with a tape around the chest under the breasts. If you get an even number, add '4' and if you get an odd number, add '5'. Example: 31 inches + 5 = size 36. (Sometimes the circumference of the chest over the breasts is measured instead. In this case '5' is not added to the result because for most women 'underbust + 5' approximately equals overbust.) To determine cup size, measure around the chest at the fullest part of the breasts while wearing a bra. From this number subtract your band size. A one inch difference = A cup, two inches = B cup, three inches = C cup, etc. Example: 39 inches - 36 band size = 3 = C cup. Bra size is 36C. The problem is that this traditional method of bra sizing usually gives a size that doesn't fit well and contributes to the belief that "80% of women wear the wrong size bra." An alternative method of bra measuring has been developed by a plastic surgeon. Band size is determined by the traditional formula but cup size is determined by direct measurement of the breast.

Actually there is no bra which comes in normal size. All bras are made for a particular shape and size. Bra size always depends on your body shape, bust size and band size. Every woman has their unique shape and size and they also have their own comfortability of bra. Two women with the same size can not feel comfortable in the same size bra because they may have the different bust shape for which bra size and style varies.
You could measure it. if there are tags on the bra that tell you, then look for it.
