But think about it, how often do you see women with their hair down outside their bedroom? Never, for as far as I can tell! And Belle goes strutting to the woods like that, with Rumple at her side (Maybe /that's/ why the evil Sheriff from the Robin Hood stories wanted to 'buy' her from Rumple :O :P)
