Part of the experience of this endeavor is to dress up in Hogwartsy costumes, but I know a lot of people don't have robes or other wizard wear laying about (silly muggles). So to help with this, I've spent some time getting together a collection of costumes. Most are from past years Halloween, witch hats, random capes and such, but I did make a few things, as well as pick up a few things at the thriftstore. They randomly had a whole bunch of graduation robes--which I swooped up. And I made a bunch of house color scarves--partly for costume, and partly cause it'll be cold.
