I had symetery issues, one breast quite a bit larger and with a different shape than the other. I had a lift on one side and implants on both. I still wear the same bra size as before, only now I fill it out better and both breasts look and feel the same. I was amazed that he was able to get "the girls" so close to identical, AND they look natural.
I only regret that I didn't do this 10 years ago. Surgery was not bad. I had very little discomfort.
