Hi , I had a ba 17 years ago. Had to have smallest size as was so tiny. I’m roughly a 34b but one side is smaller as I have scoliosis and I my curve has got worse over the years. My left side of chest is pushed out more so makes the right boob look smaller. Been offered 415 and 385 if that size fits if not 385 and smaller other side. I’m 5ft 5 and 8st 10 . Small framed but have spread round middle hips etc with age but still a 8/10. I’m worried the 415 will be huge and also will they be heavy as I suffer from back ache already. Scared I be to big but if I go smaller scares be to small . Was so disappointed after first op . The new ones will go under like the ones I have. I tried sizers but as I can’t remember exact size of implants I have it made it a little difficult to add sizers to add up to 415 so I said to surgeon I will rust your judgement . Any advise please
