I am a lean 5' 9", 165lbs, usually wear dress shirt 16-33. I ordered the grey US Medium.

This knit fits me exactly as the photo shows, except my Python arms look much better. All I need now is a mask, and I'll be ready to fight crime and not reveal my true identity.

The stitching is proper. You can put this one in the gentle cycle or hand wash cold.

I'll send mine to the dry cleaners for a few wears before washing it properly, though.

Delivery was two days after ordering with PRIME.
