This is a beautifully made shirt.  I like some of the details like the button down collar with a smaller button and the double stitching on the inside of the arm scye. The collar is stiff enough to stand up but is not scratchy or annoying.  The back yoke is lined and the shirt has a box pleat which helps off the rack shirts look more fitted.  The sleeves have a small cuff.

These kind of touches just make a shirt feel more comfortable.
