Marc Jacobs silk bow-tie, $43 at Marc by Marc Jacobs, 212.929.0304.
For years, the bow-tie was all but relegated to costumes and tuxedos, but now it's enjoying a renaissance by guys with the balls to be an early style adopter. Of course, if you've never worn one before, you likely don't know how to tie one. Sure, you could learn. Or try one of the pre-tied options (they've come a long way since your youth) like this silk one in a dapper black and navy combination. Unfortunately, they're only available at Marc by Marc stores, so you'll need to call your friend in New York (everyone's got one, right?).
