I don't know if this a repost, and I hope it isn't, but here is my idea.
I wish that we had a barber shop, so that we can change our hair. We all know people get their hair cut normally, so is there any reason for wizards to have the same hair? We should be able to cut and die out hair, and it could cost maybe 500 coins? (KI, you can have a "magic hair growing potion that makes it long, so it seems natural going from a shorter cut to a longer one.) You could also add multiple new hairstyles, and you can make it so that each world has a different type of hairstyle that you can use, all being different from the starter haircuts.
I think it's a great idea, the game's selections to make a character are a little small and we have tons of people that look exactly a like lol, my character has red eyes because it was the only thing i found that i knew a lot of people wouldnt have lol.
I do not agree with a 'Barber Shop', but I would agree to a Magic Mirror housing item or special interactive function in a house (new bundle card maybe) that allowed you to change your looks. Barber Shop, while not exactly modern, is not exactly Wizardly, whereas a Magic Mirror is suitably magical.
Perhaps they could give us Snow White's Castle, and include the Magic Mirror. it seems KI's doing enough business with Disney anyways (Selena Gomez & Nick Jonas) but even if they don't, Snow White's story is not Disney Exclusive.
