You can know a friend's bra size by asking her. If you aren't comfortable asking, then it's okay for you not to know.
You measure the rim around your butt. then you take away 6 inches. that's your bra size!
You go to get measured at a shop or something. If not just buy a random bra and try it on if it doesn't fit its not your size.

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.
You can call your girlfriend and ask for her bra size. If you aren't comfortable asking her, then buy her something that is not a bra.
You could measure it. if there are tags on the bra that tell you, then look for it.
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.

All you have to do to find out your bra size is go to any bra and underwear shop, get your self fitted and buy a bra of your size.
