cup sizes are simple.. just measure your chest diameter.. and then from your nipple to your chest.... the difference you gget from your nipple to your ribcage is what u have as your cup size

1 inch - A
2 inch - B
so on

34/75 coz 34 follows US size i think and euro follows in cm.. which is 75...

Had to learn all this coz my gf is overseas and she wanted lingerie.. //
