The 36 is your rib cage measurement in inches. The C is the cup size. So a large person with small boobs would be 44A. A thin-framed person with big boobs would be 32D! Or something.
Is that the average natural size?! so many people seem to have breast implants and reductions nowadays, but then maybe thats just played up by the media
most peoples breasts get bigger when they put on weight, unless they're particularll unlucky isuppose. and we're all getting fatter, which is probably why the average size seems quite big(ish)
I'll bet that every girl who asks herself that question answers herself with "Whatever it is, it isn't my size!" No-one's average, everyone's different. BTW I sent a birthday card to my less-than-well-endowed sister. On the from it said "Inside this card is a joke so funny that it will make your t1ts fall off". Inside, it said "Oh - I see you've heard it already!!!!"
I'm now a 34E after a reduction from 34G beat that =p and tbh, i still think that they get in the way too much, men dont get past your tits when they talk to you
