Wife liked it on me.
Size: Large, Color: Olive Green
A good value, and most especially my wife loves it. A bit long in the sleeves, but then, I'm 5'-7" so that was expected.

Cotton
Color: Blue, Size: Medium
I was impressed with the quality of this shirt. My son wears it to church. It is cotton. It washes and irons like the cotton shirts from years ago. I like cotton so much better than blends even though it must be ironed after washing. The shirt looks high end.
