What's the problem to start at 18 years old? when you are mature and u have finished the school, i really don't like children with woman dresses.. i don't like girls who left school to model.. there are many 25 years old girls who are still doing very well, and absolutely they are not OLD! if u have 6 year of good career modeling it s not bad at all.. what s the point starting at 13? At 13 people should play sport and go to pijama parties!
