This is a maker that lets you use assets you make in the other Magic Makers to create your own dressup game. (The kind were you click the arrows to change the clothes.) It is still in the very early testing phase, so not everything works. But if you want to know a little more then click here. You can view example dress ups on the Dress Ups page. You need to be a member for this one since it needs assets to work ;)
