I pulled this together in a hurry for the eve of book 6's release. The skirt, shoes, shirt, tie, and sweater are all store bought. The robes are my college graduation robes with colored lining, hood, and Gryffindor patch added. I'm planning on getting a better tie for the book 7 release (mine is the official WB one and the colors are really off! The burgundy looks purple in sunlight), and eventually I want to knit a sweater that'll look better. To go with it, I found a plain black messenger bag and added a Hogwarts patch but I need to find a new bag because the straps are fraying beyond belief!
