Right for me. I notice it a lot but no one else really does unless I point it out. XD

It sucks sometimes, cuz I have the exact same problem as vietcaterpillar. Left one is too small for some of my bras. XD

Haha! Well, I've always thought that my right boob was slightly bigger (:

Leftie is bigger. I checked XD It's not that noticeable, but I can tell, haha.

my left boob's bigger. it's not noticable to anyone besides me

Right side :P

My left boob is slightly larger. It's not noticeable except to me though, lol.

same XD well at least i hope it's not noticeable XD

I dunno, I think my left is bigger, its hard to tell :3

I think it's my left one .. still love 'em though. :D

my left one.

I do believe my left one is slightly larger. Not noticeable though.

I think my boobs are equal. XP

Left is just a little bit bigger then my right. Not many problems with bras. :P

The same I think. I can see no difference in size.

This. I heard some statistic somewhere that said most women's are uneven. My right is a little bit bigger ): it's really annoying. Nobody else really notices, but I do.

Left boob=bigger. So... awkward. xDD

Left. My left is significantly bigger than right. Buuut- You couldn't tell if you looked at me regularly. You'd have to be a pervert to know which one is smaller. Or my mom, because she's nosy and just yeah.
