Meet Perry, our Platonic ideal of a button-up. Fit to perfection, it’s neither slim nor oversize, but the perfect in-between. Good for tucking, but equally nice left out. It’s cut from a crisp Italian cotton infused with a touch of elastane (3 percent, to be exact—just enough to ensure a little give). And when it came to the finishing touches, we went for the subtle but impactful: grosgrain trim on the inside placket and an embroidered GWYN logo on the wearer’s left.
