I'm normally 32C and bought this in C75. This bra is good for shallow and wide shapes. The cups are soft and the padding is a little less aggressive than the Peony Lace style. Other than that, they're quite similar in my opinion (same straps, same 3 hook fasten in the back, 2 side boning on either side, high underarms)!
Very soft cups and pretty design! I prefer bras with some separation between the cups, which this has. The padding is removable so if you don't like it, you don't need to keep it in there. The straps are on the wider side and the back closes with three hooks. I normally wear a 32C (shallow and wide) which usually converts to D70, but because I read that Japanese bands can run small, I went with C75 and that seems to have worked for me.
