She can do this with the help of her natural youth that many of them carry in their young age. At the same time she can do modeling for those products as well that are targeted for slightly older people. For that particular outcome she may need to take the help of some makeup and she can look erotic and sexy like a mature girl She can keep on doing this for a very long time.
