I bought this as a souvenir at the Harry Potter New York store that opened in New York. It's a simple gray cotton t-shirt with a slightly distressed look. It has ribbon tape accents on the shoulders and a stylish rubber print on the left chest. The size is unisex XS, which I purchased as a women's M. I think it's a pretty rare item. Shoulder width: 44cm Body width: 43cm Sleeve opening: 16.5cm (flat) x 2 = 33cm Length: 60cm Measurements are approximate. Material: Cotton Color: Gray Sleeve length: Short sleeve
