The unofficial uniform of summer, our short-sleeve shirts are the easiest way to stay cool. They're not the kind you'd see in mission control during a moon landing (although we like that look too)-they're our famous washed shirts but with shorter sleeves. This linen comes from Baird McNutt in Ireland (Irish linen is considered to be the world's finest, and Baird McNutt's the finest in Ireland) and looks better a little bit rumpled, meaning you'll look even better after that nap on a hazy summer day.
