Yeah, most women are lopsided just like testicles. In fact even my ears are lpsided and due to scoliosis from being hot by a car at 16 my left shoulder is 1 inch longer than the right and 1.5" shorter than the right. My 2nd wife was lopsided after breast feeding our son who favored the right so much he would practically only feed from it. She would have to pump the left side to keep it from hurting. Once he was weened at a year sand a half she was lopsided but you had to really look to see it, but she sure as shit would notice it every time she was changing shirts bras , drying off.
When I was 18 and living in Medford I had a girlfreind who had one C and one B so yes a very noticeable difference. But damn, they were such perfectly shaped breasts!!!, I still miss them!!!Don't worry Femme, I'm sure you look great!
