Continuity error?

I doubt it is, it's probably intentional but I just can't figure it out. It's also not that important but it's annoying me for some reason.

Anyway, went to watch it for the second time in cinemas today and noticed that when Mary is standing outside the store, her hair is up, but when she's in the basement, it's down.

It does frame her hair better for the close up where she finds the 'door' but still a detail that took me out of the movie for a moment
