amphi-gorey said, "Hi! Cup size is actually standardized. Each cup is one inch of difference from the band size. A C cup will always be 3", whether it's from Nordstrom or Victoria's Secret. A G cup is 9", so no, someone who wears a 32G will not fit a 34C. Your previous commenter is simply wrong. (There is a slight complication in that the US system is different from the British system because they don't use double letters except for D. If it's an American G, then it's 7". Still won't work as a C, though.)"

Hi! Sorry to say that through experience I disagree with this, even within one country bra sizing varies brand to brand! In England anyway, maybe in the US it is standardised but sadly not like that here at least!
