Once upon a time, donning a sweatsuit in public was like hanging a sign around your neck that said: “I’ve given up.” But those days are long gone. To the relief of many (and the horror of a few), we’re now living in a golden age of comfort, when sweats aren’t just acceptable — they’re actually stylish. Wear ’em for a city stroll, a casual lunch, or a long-haul flight, and savor their cushy, elasticized ease without sacrificing an ounce of dignity.Not just any sweats will do, however. Lousy ones will still look tragic (and pill, shed, shrink, and rip at the seams). We tested nearly 80 women’s, men’s, and unisex sweatshirts and sweatpants to find standout sets for a range of tastes, bodies, and budgets. Whether you’re in the mood for plush fleece, bouncy terry, fluid jersey, or luxe cashmere, our 24 picks offer an array of terrific options for cozying up — or venturing out.
