Thrown on after the gym or as the ultimate in weekend lounging attire, the hoodie is the go-to for off-duty days. Choose classic gray marl and navy for a simple sportswear vibe or try a hit of color to pop against dark denim. Up the ante with luxed-up versions with varsity-style contrast sleeves, shell trims and seam detailing. Look to Diesel, Nike, Dolce & Gabbana and Polo Ralph Lauren.
