German shop simply do not have bras big enough so they sell you a bigger back size and smaller cup size. Many women wear the wrong Bra.
My guide
when you can give Spannish sex you are bigger than a C
When you can give spannish easily you are above a DD
When I need two hands to hold one tit you are a G
When your tits go from your shoulders past your waist and are the size of my head you are HH
