Josh Bach, $42

Quirky designs like constellations or the signatures from the Declaration of Independence set these pure-silk neckties far apart from the run-of-the-mill. If your guy has a bit of trouble tying his neckwear, get him the one with instructional photos on the tie itself. If he does know a Windsor from a four-in-hand, choose one of 78 other designs.
