Megan Fox Ass. Crazy Pics.

I need help updating my image? ok im 19 about to turn 20, but need help with my look, my long blond hair to my lower back and I usually put a lot of makeup to achieve that look naturalish (ie, all colors Nutral). But I see my age if I do normally dress that looked about 12, but if I try and dress more I look like a 12 year old trying to look 30
