Classier than keeping those easily lost, flimsy plastic sticks that came with your last work-shirt bundle in a Ziploc, Swiss Stays are durable collar stays that come in a convenient, old-fashioned-Zippo-looking metal case. Available in brass, PVC, stainless steel, and titanium (six in a pack; $8-$50), the functional accessories feature extenders that fold in or out—like your boyhood Swiss Army knife—to fit all 24 styles of collars you’ll encounter. (You knew that many existed, right?) Tip: A leather travel set or sterling-silver version make luxe gifts for grads or business associates. Join fans like the editors of GQ, and management at the MGM Grand in Las Vegas and The NoMad Hotel and The Mark Hotel in Manhattan, who offer Swiss Stays to guests. Find them in the county at Brooks Brothers, Macy’s, and Men’s Wearhouse; www.swissstays.com.
