I'm in between A & B. A is too small, B has extra space. The Italian '1' seems to fit better. It only comes in padded. I have sloping shoulders so bra straps do not stay up. I have a little elastic thingy that is supposed to hold them up--that means they don't fall down as often.

I go without as much as possible. Working from home makes that possible most of the time. I think I'm getting saggy at the ripe old age of 35! lol
