Since I'm more of an S leaning towards M, it's a size that I can usually wear even if I'm an M. Length 57cm Shoulder width 41cm Chest width 43cm *Measured by a layman with a tape measure. Has pockets. The lines are very beautiful, and it's easy to throw on and has been useful. I've used it often, so there's some wear and slight pilling (mainly around the underarms), but I think it can still be used.
