Nice shirt, odd fit
Size: X-Large, Color: Dark Grey, Size: X-Large, Color: Dark Grey
This shirt looks and feels very nice, and there's no weird stitching or loose threads, but the fit was a little off. It was a little short on my husband who is 6'1", but if he stands with his hands down it doesn't really LOOK too short. It's when he raises his arms for anything that it seems weirdly tight across his the chest and it pulls the hem of the shirt up quite a lot. This could just be a body type thing, but he doesn't have that issue in other shirts the same size and style. It's a shame because the shirt itself seems really nice.
