What you need to do: Calling all Harry Potter fans! If you associate with a Hogwarts house, you might as well flaunt it. Wear a blue checkered skirt or pair of pants along with a blue sweater with a large letter "R" on it to sport your love of Ravenclaw. To fit in with the Gryffindor kids, wear a red checkered skirt or pair of trousers, and put a bright yellow "G" on a red jumper. Let the magic commence!
