The sizing shown is not in US sizes, the XL is close to a US medium. I can't wear it but luckily it fits my wife.

The quality is actually very poor. I found 3 significant flaws in just a cursory look. The bottom hem is twisted and pleated in several places, the collar is about a half inch out of line across the zipper, and one of the seams has a broken thread that will need to be repaired. I make better shirts at my kitchen table.

Interesting choice with the shoulder seam too. They've serged the sean then top stitched it flat instead of using tape. That's the way i do it because it lays nice and flat, but ive never seen that on a commercial garment.

Material is ok. It is italian wool, not merino. It's probably better suited to purpose as a tougher fiber than merino, but it's going to be a bit rough for wear against skin. It pilled pretty much immediately, but that is typical of wool blends.

Just received this shirt today in the mail and was very excited to get it. Im 5'11 and 200 lbs and ordered an XL. It is definitely a European sized shirt, as there was no way it was going to fit me. Looking over the quality of the piece though it is an amazing deal for the shirt, the wool is pretty soft, if you can get the sizing right, its a must buy!
