Summer layering is a difficult task. High humidity makes many blazers and jackets too oppressive to wear between June and September. Fear not, though. There are still plenty of summer-friendly alternatives, including, of course, the linen jacket. Whether used in a safari jacket or an overshirt, linen’s breathability keeps the wearer from overheating, and its less formal appearance lends it an air of insouciance. After all, these are garments that look their best a tad rumpled.
