Harrods of London Men's Long Sleeve Dress Shirt Size 15.5/39 which is a Medium Blue and White striped Made in Italy. Purchased in London. 100% Extra Fine cotton 200/2 Please see pictures. I tried to get better measurements. Looks like just over 17 in across the back shoulders, and I would estimate the sleeve length at about 34. Cuffs do fit on the narrow side so it does not move over the wrist. Maybe worn once or twice. Dry cleaned.
