Only a small part of a man sticks out at the collar and cuffs of the shirt he wears, so the shirt counts for a lot. After mulling this over, I've come up with a shirt whose cut fulfills its responsibility: the Peterman-Cut Shirt.
The Peterman-Cut Shirt is fuller in the body and arms. Why? More freedom of movement, and more flattering to most physiques.
The shirt is longer, so it stays in your pants when you dismount your horse. The collar has generous 3-1/4" points, a solid platform upon which to present your face to the world. The 1-7/8”tall rear stand won't slump down miserably out of sight under your jacket collar.
As for the execution, it's unstinting, e.g., reinforcing gussets at the point where the back, front, and side seams meet (a mark of true craftsmanship).
Peterman-Cut Check Shirt (No. 2244), as described, in pure cotton, pattern-matched throughout. Button-down collar and adjustable button cuffs. Seven button front. Patch pocket and rounded hem.
Reporting for duty, sir.
Colors: Green check on White.
