The casual shirt jacket got a premium makeover for spring. Brands have taken the classic silhouette and upgraded it with leather and suede, creating investment-quality pieces of light outerwear. While the prices reflect the quality of the materials, the garments will last for the foreseeable future, developing patinas unique to the wearer. Check out timeless designs from brands like Iron Heart, Indigofera and Ralph Lauren. A decade from now, you won’t regret the investment.
