Casual Plaids

They're the double-duty workhorses of your cold weather wardrobe. The right tartan on a casual cotton shirt gives your fall look a rakish, seasonal charm. Sporting a plaid shirt at the office with a dark, textured tie will separate you from the other guys wearing simple, solid button-downs. Or embrace the current '90s revival happening in menswear and pull an easygoing flannel over a loose T-shirt, roll up your sleeves and leave it open. Or make like Kanye or Pharrell and tie it around your waist when the sun's out.
