Personally, I would probably add either a way to have facial hair be permanent applied to your character (so it would also show up with all the gear that, for some odd reason, was made to remove it when being worn) or a new type of accessory: wristwatches.
With a wristwatch, you could customize the look and color of your in-game clock while looking cute/fashionable at the same time. It would also be a way to take a small dip into the past and bring back the clock UI from previous titles with an HD look. Most of the normal watch designs could cycle through simple seasonal designs or change along with the weather too. Of course, there's the option of it just being a phone app and you buy them via the Nook Stop or from with the clock app itself.
