Worried about how to wear it correctly? Fear not. Online retailer Neckties.com sells pre-folded cotton ones for $7.95. If that seems like cheating, they also provide how-to diagrams that will enable even the most fumble-fingered to master such evocative shapes as the Astaire, the Cagney and the Winged Puff. Just remember: never match a pocket square exactly to your tie.
