I'm usually one to get a little bent out of shape when hair is mis-represented as longer than it truly is, but if Ms Rapunzel is going to undersell the length of their models' hair, I'm ok with it when it's longer than advertised
Hard to say for sure what the length is since it falls past the frame so much, and it's in a ponytail or swinging with her head back often, but I think she might be at upper thigh.
Definitely past hip though!
