Do I have the "Disney princess look"?

I think you could reasonably be a face character for Elsa. :)

That being said, since you're only 100 pounds at 5'6" (I hope you're exaggerating something, because that really isn't healthy!), the princess costumes would probably not fit you. They only come in a few sample sizes, apparently.

I think u'd cut out 2 be Elsa, u'd just have 2 grow ur hair out a bit. But other than that, u'd make a great Elsa!!
