Summer 2023 is devoted to the season’s signatures, from seersucker with a modern twist and brown loafers that go from street to beach bar, to a traditional shrimp boil. We trip down the Pan American highway and through Tuscany on the retro-cool L’Eroica bicycle race, then dive into the archives of Rat-Pack favorite Anto of Beverly Hills and find warm-weather inspiration in the swashbuckling style of Peter Beard.
