thatnx hun, it depends on how much breast tissue you have, i was an empty A, i didnt have that much tissue but by having overs i could have gone for a bigger implant than unders, but each surgeon says diffrent, i had dr singh, hes known for giving people bigger choices of implant than other surgeons and people say he prefers overs, not to sure if thats true though. it all depends on whats best for you the surgeon will advice what he thinks is best xx
