This was my first Genteal purchase, and it certainly won't be my last. This is such a versatile shirt that I can dress up for dinner, or, more likely, wear on the beach and lounging around the house. Extremely lightweight and breathable, but keeps it shape and I could certainly wear under a blazer. Genteal even included a quality wooden shirt hanger with my purchase- classy! For sizing reference, I'm 6' and 175lbs with average build and the medium traditional fit is just about perfect.
