I have a natural 'D' cup and they don't look plastic. D=
I did say most girls. =P Not all. =P
But it really does depend on your body shape as to what looks okay and what doesn't.
My friend and I are both currently A cups.
However her body shape is a bit bigger than mine and wider around the chest area.
So when I go in for my C cup she's going for a D.
I don't understand why anyone with a 'C' cup would need to go up a size but she'll probably regret it after, especially if it's something she's doing for someone else (i.e. her friends). She should be proud of the fact that she's the only one of them that hasn't had plastic surgery yet.
I agree.
She really should be stoked at the fact that she has a naturally awesome cup size and that she'll be saving $12,000 on having to have them done, unlike her friends.
