The jacket has shoulder pads that don't necessarily show on the image in the purchase area. Pretty pronounced so if that's not your thing definitely stay away. Got lucky and it doesn't look too bad on me but it took so long to receive the package I don't feel like going through the refund process so I'm dealing with it. Quality is great tho

Nice Coat Not So Great Packaging

Size: X-Small, Color: A-grey

Nice coat but packaging needs to be improved. It arrived not properly folded and as a result it was completely wrinkled. Took some work to iron so it looked as advertised. Packaging for such things has to be reviewed.
