Thank you for viewing. This is a navy striped tailored jacket from Comme des Garçons Homme. The material is polyester. I believe it is very easy to use as an inner layer during this season and as an outer layer in early spring. The size is listed as S, and the actual measurements are approximately shoulder width 44cm, body width 50cm, sleeve length 59cm, and length 75cm (amateur measurements). While there is a sense of wear typical of used clothing, there are no noticeable scratches or stains, and I believe it can still be worn. We welcome immediate purchases and questions. Thank you.
