Princess Dress Up Aprons from Fireflies and Jellybeans
My youngest is right smack dab in the middle of her princess dress up phase. One of the rules we have always had about playing dress up is that you have to keep your real clothes on under your princess clothes. This comes in handy when you have multiple friends over playing dress up. I love these fun princess dress up aprons that Fawnda created because they sort of promote my wear clothes rule. And they are probably a thousand times easier to get on and off over clothing than the full dresses that are crammed into the dress up box in the girls room.
