How do you measure your bra size?

-I've been on a few websites, put in my measurements and my bra size almost always comes out as 34AA which just is NOT right! Most of my bras are either a 34B or 32B and all fit fine. I'm very busy so generally buy my bras online therefore getting fitted isn't really an option at the moment but I'd like to know my exact size as I won't be trying them on before buying.It changes from site to site, shop to shop. There isn't really a fixed standard for them.



Try this with the ones you have at home, see which fits better:

-if you lean forwards, your boobs should fill your bra, not overspill or they're too small. Stand up, and the bra shouldn't have moved. If it's ridden up, you need a bigger band size (number). If your bra leaves a mark, you need a bigger band size. If it's tight under the arms, you need a bigger cup size. If there's any gapping on the loosest clip, it's too big in both size and cup most likely. Hope this helps.Have your dad help you into your bras and he will let you know.
