The biggest issues I have with vanity/wardobe are
A. It's two separate pages, so tweaking hair or outfit to go with the other is a big page-switching pain in the bum
B. You can't do it in game, so if you want to change your outfit in the middle of playing, you must abandon your character while you figure out what to wear (unless you're clever enough to suspend in decorate mode).
My solution? Craftable mirrors: decorative AND functional. We could make them out of crystals or diamonds or Shiny Objects of Zero Value. When one clicks on a mirror, it would go to an in-game menu featuring all of vanity AND wardrobe (but perhaps clothes one already owns). Vanity and wardrobe all in one place, in game, AND as an added bonus: a use for Shiny Objects.
