You should have the body you want, if that's natural or small then go for that.
If you are asking for the input of someone who loves big tits then the answer is probably about 1000cc. Depends on your overall height and chest measurement. Up to 2000cc looks pretty great. Of course this wouldn't be right away. Gotta work up to it.
I don't get why women do this to themselves. I guess she was pretty once. But those tits are completely out of place and don't make sense, and these lips... Why would you ever even think about putting silicone in your lips...?
Seems just like an expensive health hazard to make yourself unpretty and loose a lot of money.
But I guess this is all subjective (though the the objective majority seems to have similar thoughts).
