^Yeah, we want sub-conscious, not 'Oh, wow, Jill finally undid the massive French hairstyle that she wore in England' or anything.
I took it from the book that Jill looks to keep clean and tidy, at least to some extent (so calls the enchanted Rilian a 'selfish, self-centred pig' because he didn't show them where they could wash-up before they ate. And it isn't just because she wanted un-germy hands for eating, because she proceeds to wash her face. Thus, I suppose she is not all too happy when she is dirty, grimy, etc. I thinks she should be this way in England and in Narnia.
As far as changes, I would like something like perhaps a tight braid in England, and then loose waves in Narnia? That would work because in a braid, if Jill has wavy hair we would not see that except for at the ends. And it does make perfect sense to pull your hair out of a braid and for it to be wavy, at least for a little while.
Seriously though, I would like for the prettiness of the curl/wave whatever (majority of people say that her hair should have some 'body', one way or the other) hidden while in England, and then be revealed in Narnia. If that doesn't happen I wouldn't mind, though- just an idea. Plus it could grow longer throughout the movie, and Jill could be more and more 'free' with it. Like maybe she still pulls it up somewhat or braids it loosely, but by the end of the movie her beautiful waves/curls/whatever flow free and uninhibited, framing her lovely face.
Thoughts?
