Keeping your scarf tied in a way that stays put, keeps you warm, and doesn't look sloppy is a challenge for most of us, but here are two foolproof ways to get it right. For a long, thin scarf, try a loop. Hang one-third of the scarf on one shoulder and the rest on the other. Bring the long end around your neck, and adjust the ends so they meet (pictured, left). When you have a thicker scarf, make like a European: Hang it around your neck so the ends are evenly matched in front and tuck them into a suit or warm-weather jacket.
