This is a fantastic Paul Smith Men's Shirt. It is a size large. It measures 22 inches armpit to armpit and 27 inches from top button to the bottom of the shirt. Across the shoulder it runs 18 inches seam to seam. And the sleeve length is 35. The fine cotton, the mother of pearl buttons, and the outstanding craftsmanship all add up to a great product. Paul Smith is fashion forward, modern, a slimmer fit, but always classic! This shirt was very very expensive. It is being offered for a fraction of the original price. A great opportunity to own a Paul Smith classic for a great price!
