Keep it Buttoned
Button holes are tiny. I recommend keeping it buttoned and taking it off over your head. Unbuttoning it the first time was super frustrating and I felt like I was manhandling my new shirt. Maybe the holes loosen up over time. I’m not taking the risk. I am 6 feet, 180 pounds with a 40 inch chest, athletic build and the medium size is perfect. Not tight, not loose. Beautiful shirt. Still 5 stars. Keep it buttoned!
