hi shotts, I had 380 overs from a 34B and now 34E – but i did ask for a small D and think they look more of a D although they measure an E if that makes sense? If you want to look a C then you will probably have to measure a D so 340 should do it. Although after you’ve had them done the dreaded boob greed kicks in, and you’ll wish you had gone for the 380’s!!!!!!!!!!
