The listing, Studded Ravenclaw shirt from Universal Orlando has ended.
I bought this from the Wizarding World of Harry Potter at Universal Studios Orlando. Unfortunately for me, it's TOO small. I usually wear size medium (I'm size 6/8 most of the time) but this runs SMALL. It would be better for a size S or XS. I did wear, and wash it, a couple times but it's just too small for me to wear comfortably. My loss is your gain!
