I've always gone along with this theory too. My left breast is smaller and I am right-handed. I figured since I have always been right-side dominant I built up those muscles and tissue more throughout life.

I can take this theory even further. I used to be an athlete and my whole right ARM was larger than my left! So I was definitely conditioning my right side to be dominant growing up. [/align]

Thanks, Jenn!
Hmmm, maybe it doesn't matter then! I'm a righty and it's my right tit that's smaller, but only by a very small fraction, really. I've been a drummer all my life, so I gave ALMOST equal time to both arms! Although, my left (snare arm) didn't get as much of a workout as my right (cymbal arm).
