This is the only Harry Potter specific item I brought to wear on my trip. I bought this Gryffindor sweater directly from the place that made it for the movies way back in 2009 (I think, maybe earlier.) Fortunately for fans they sell them at the theme parks now. But I kind of like that mine doesn't have the WB/Universal logo anywhere on it. Makes it more special, ha ha.
