This is an Adidas by Stella McCartney hooded half-zip top. The size is International S, which is equivalent to Japanese OT. Flat measurements are approximately 56cm in length and 40cm in width. (Please note that these are amateur measurements, so there may be some errors.) The material is 80% polyester and 20% polyurethane. It is a new, unused item with tags. The chic floral pattern is a very lovely design. The Stella McCartney logo is on both sleeves and the back. The half-zip allows for temperature adjustment. It has a very tight design and is a thin top. #AdidasbyStellaMcCartney
