Each princess gets a room of her own, which is what makes this longer than the thumbnail suggests.
Elsa, Anna, Merida and Ariel have built a shared treehouse, and you furnish four separate spaces: a bed, a rug, wall decorations, a sofa and a coffee table in every one. Only once the rooms are done does the dressing start, and the clothes are deliberately cosy rather than formal, since the premise is hanging about indoors.
Four rooms is a lot of furniture. Give each girl one signature colour and repeat it at three sizes in her room, and the spaces will read as one treehouse instead of four unrelated builds.
