This is a collaboration jacket with Knicks that was sold the year before last. I purchased it from the Kith online shop. It is guaranteed to be authentic. It is new and unused. I am selling it because I haven't had a chance to wear it. As it is an autumn/winter item, I think it's perfect for the coming season. Please consider it. Measurements are approximate. Please note that there may be some errors. Shoulder width: 54cm Body width: 66cm Sleeve length: 64cm Length: 75cm
