There are myriad reasons to despise Rick Santorum and his views, and as many reasons to bemoan the sartorial preferences of all the presidential candidates, even Mr. Cool himself, President Obama. But wearing sweater vests, seemingly the mark of a square, a dweeb, or whatever, should not be a reason to poke fun at or demean one of the more extreme politicians of our age. Remember when cardigans, the Mr. Rogers look, were the object of scorn? Today, no hipster worth his Williamsburg digs is without one. Tie bars? Do Brooklynites even know you can wear a tie without a clip? Brogues? Bow Ties? Need I go on? The sweater vest can look square, professorial, or worse. But it can be a damn useful item of clothing, especially if worn under a suit or a jacket, when sweaters with sleeves can add unseemly bulk. This one, in a single ply cashmere is almost twenty years old (from an era when cashmere really came from the throat hairs of the Kashmir goat in the himalayas), woven in Scotland, came from Anderson & Sheppard. Yes, the Saville Row tailors with a famous and infamous client list, clothiers who’ve outfitted everyone stylish from Cary Grant and Fred Astaire to Prince Charles. If it’s good enough for them, it’s good enough for me.
