Very nice quality for the price point. 100% satisfied, and will definitely be purchasing more. I found this to be true-to-size > I bought a medium, and I am 6’2’ with a 40” chest 15.5” neck, 30” waist - “athletic” build, and this has a nice, nearly tailored, fit to it. The brown buttons (on the white) are a nice stepped-up touch, which had multiple people ask me where I got my shirt.

Know your body type.

Color: Navy Blue, Size: Large

I really liked the look and the buttons when I ordered it but I wound up returning only because I have to have a slim or fitted cut for any shirt to look good on me. This shirt did not hug me in the sides and looked like I was wearing someone else’s clothes. Nice shirt and good quality but it didn’t fit me personally. I did consider having it tailored but the cost of doing that was almost as much as the shirt.
