There are few designers coaxing men’s wear to new frontiers quite like Alessandro Sartori. His fall ’21 Ermenegildo Zegna collection, shown last month in Milan, was dubbed “The (Re) Set,” and it merged loungewear, knitwear, and outerwear in a sort of pandemic alchemy: clothes that are terribly comfortable while retaining the spirit of dressing up. Sartori, who has been at Zegna since 2016, has committed himself to sustainability as well as to style. He has implemented a program called “Use the Existing,” which puts upcycled materials to work in new products, and uses organic merino wool sourced from Zegna’s own farm, in Australia. But above all, he aims to design pieces that will be used and treasured for years, and decades, to come. Herewith, he shares his key components to the good life. —Ashley Baker
