I am trying to help a friend shop for a new bra now. I helped her measure herself to get a good starting point. I got 34 underbust, and 41 overbust... 43 if she leaned forward like some things say to do... So that would make the cup size 7-9 inches bigger than band size right? So in US sizing, that would be a 34DDDD/G-34I? Any suggestions on what size to start with? If it helps any, she's had implants and then had 2 kids, so her breasts have gotten bigger. Last baby is 9 months old now and she wasn't able to breastfeed, so that shouldn't be a consideration.
