I realized this when I noticed that like .. one bra cup was perfectly filled while the other one (right) was a bit loose. And I've noticed other girls who have like different sized boobs o_O. It's kinda weird.

Why does it happen? Maybe it's cause the heart is on the left side so more blood gets pumped there? or .. maybe we need more cushion over it? Or like since I'm a righty I use my right arm more so .. I guess the extra exercise takes off the fat from the boobs?

It's not like something too obvious but when you're wearing bras they're suppose to be symmetrical so .. o_o

lool awkward question kinda?

it's normal for one to be bigger than the other o-O
also goes for feet, hands, legs, arms XD haha
only if it's too visible and obvious or the person becomes too conscious of it then surgery is needed to correct the problem~

My left is bigger XD

Whoa, so far, 3 votes, all left boob LOL

^ 4 left boobs now!
so yeah, my left boob is
bigger than the right. but
you cant really tell. only
from my angle. which means
nobody can tell. haha.
weirdd.. all lefties.

-Bee.

whoa i always read about how some girls have one bigger than the other, but ive never heard anyone i know complain about it
mine are both the same ^^

LOL! My right one is bigger o_o
And I'm a righty, too, so it's probably not the exercise theory. xD
But I thought it was something you grow out of?

oh im not complaining o_O i was just curious

Left for me ~ I envy those who have same sized boobs ~

my right one is bigger, if i'm not mistaken.
Just slightly bigger, I wouldn't notice it unless I stare at them really hard.

i think it's because my right is the dominant side.
I write with my right hand,
my right eye and hand is slightly bigger than my left.

i know one of mine is bigger than the other, can't remember right now and don't think i can check right now but it's perfectly normal so don't worry nothing on the body is symmetrical, one thing will always be bigger or 'lopsided' than the other like eyes, boobs, testicles, etc.

ima guy. but my left "boob" is bigger XD

it's just cause of how you grow!! we learned this in health class 50 hundred years ago.

i always thought most people had bigger left chest/boobie because that's where your heart is.. so it makes that side be bigger a little.

my left one is bigger =x
------------

my left one is biggger :x
lols I thought I was the only one who had this problem because most of my friend's boobs are the same sizee :[ and oncee I told them in the locker rooom that one side is bigger than the other, they told me that I'm gonna get breast cancer
hehes I don't feeel left out now after seeing the results in the poll

I just noticed how uneven my breast were when I was in the dressing room!
I was just dancing around in front of the mirror naked LOL and I was like..WHAT THE HELL?
My right is bigger than my left's!

yeah it's very annoying. if only they were the same size i wouldn't be so conscious about how they look.

humans are lopsided freaks. =]

My mom told me it had to do with which side was more dominate. Like I'm right-handed so my left boob would be bigger and so forth. Haha

There isn't much difference, but my left one is slightly bigger.
As if I had any.

ommggg it's so annoying my left is bigger and i'm really self concious abt it and stuff...and i really hope it grows out to b around the same but i'm 15 already.. T___T well turning 16 this year..

My left boob is bigger and it really bugs me. 'Cause one cup will be filled perfectly and the other one will be a bit loose. It annoys me so much. I envy girls who have evenly sized boobs. And I've always heard from people that if you have different sized boobs, you'll get breast cancer.

it's natural for ur left boob to be bigger because ur left side is where ur heart is and the heart is what give the left size an extra push...

my left is bigger. SO ANNOYINGGG. it's like all the fat travels down to the left boob T_T
it's something that's got to do with your breasts being asymmetrical. so it's normal.

my left's bigger. i think its because i'm a righty.

LOL. My Left boob is fills in the bra cup better than my right =[.

Even though its not that noticable(but to me its noticable) I wish they were the same size!!!!

whoa. im like one of the few with a bigger right boob. weird.
it natural for one of your boobs to be bigger than the other so it doesnt matter to me. unless ones like C while others A, no one can tell

i was just figuring out which one is bigger earlier today then all of a sudden i found this topic haha. but yeah, my left ones bigger

my left boob is bigger.

i'm not alone

I know! I thought the same thing when I saw the poll.
That's weird.. I wonder why it's the left.

my left is bigger
but i'm a righty so idk how that works..
but yea like it fill my bra better than my right side..
haha

I read once in marie Claire that the majority of women (based on a nation wide poll) that their right boob is bigger - weird considering how many of the people that have posted in this thread have bigger left ones. Well, anyways, i have a bigger right. Sucks, but what can u do about it? I embrace my lopsided boobs o^_^o hahaha

my left one is bigger
I used my right arm a lot so I'm not so surprised
it's annoying though lol

It's normal for one side to me bigger.

Theoretically, your left boob should be bigger than your right, because of some lymph node in the area, plus more nutrition. Something like that, I saw it once in a book that explained it.

So it's normal!

right one is bigger.
it drives me bananas!
