Size: L Flat measurements: Shoulder width 54cm, body width 58cm, length 60cm, sleeve length 55cm. It should fit someone who usually wears a size M to L. As you can see in the photos, it's in excellent condition with little wear, so I think you can wear it for a long time. Please check my profile before considering a purchase.
