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, but I'd have preferred the collar to fit a little closer.  The offset zipper is the detail that caught my eye, and it definitely works well with this knit.

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.
