Always go bigger trust me! Personally I think they only look really big for a small frame at 500cc and up.
I had 400cc from a 34 A, I’m a size 6, 5’7. 14 months post op now, and want to go up to 500cc but was only aloud 400cc as I was small and tight skin before.
Always go bigger, you never hear girls say they’re too big!! Lol
