I purchased this at the Harry Potter Mahou Dokoro store, which required a numbered ticket. I was thinking of wearing it, but I don't think I can bring myself to because it feels like a waste. I'd like to sell it to someone who is looking for it. Product Size: Free Size (M size) Chest: 104-112cm, Length: 70cm, Width: 58cm, Shoulder Width: 53cm, Sleeve Length: 25cm Material: 100% Cotton
