My left one is bigger, but my right one is perkier.
So far both of my GOOD FRIENDS are the same size. Yay.
I wouldn't class myself as extrememly lucky. My one boob was bigger than my other boob until I was about twenty. And I was an A cup up until 20 as well. Now I'm a perfectly symetrical C cup. I think I deserve it :P
Yeah, that's true. There most likely is a difference between my boobs but it's great that it's so small that I can't see it :D
neither, my boobs are perfect.
actually I honestly just can't tell. maybe I'll get my fiancé to check for me later
did you know that if you squeeze the bigger one real hard they will both even out?
you first
Oh wow, I can honestly say I've never thought to check my ball size difference. I dunno, I think ignorance is bliss. Less imperfections to obsess over. :O
I am absolutely convinced my left boob is slightly bigger. My boyfriend claims otherwise.
I have no idea, but they look pretty much the same to me.

I think my right's sliiightly larger than the left but they're both pretty big so I think the only way you can tell is if you're looking at them from my angle when I'm wearing a low cut top.
my right boob is bigger than my left ~! it isn't noticeable but it sucks in certain bras when leftie doesnt fill up the entire cup :( oh well
I think, on average, at least for breasts, the one that's on your dominant side is usually smaller.
I'm right-handed. ;)
I think my right boob is a little bigger, but I can't look because my sister is in the room with me. Or they could be the same size. I don't know. I just know they are really big
