Harry Potter Ravenclaw The knit sweater and scarf were purchased at the London Studio Tour, and the tie was purchased at USJ in Japan. They have been stored in a dark place after being used a few times. All three items have been cleaned. The knit sweater is size S, but it's a UK size S and unisex, so it may be a bit large. There are a few inconspicuous pin marks on the tie (photo 12).
