She is probably a lot older than she seemed. My daughter is 21 and she often looks as if she's still at school, she doesn't look old enough to be driving a car. But as we get older we find it more difficult to judge age.
She was probably 21, but I may be wrong.
I got my first tattoo at 16 and last at 21, they are all in hidden places, but I can expose them if I wish. As far as piercings go, I think ones that deform the face can cost some a career, other than that the holes can close up and you can remove piercings when you feel like it or circumstance requires it.
