IF CAPES WERE FASHIONABLE … Jean jackets, bell bottoms, Polo shirts with the collars flipped up, mandals — they all successfully crossed over to this side of acceptable. So why not capes? Think of all the colors, fabrics and styles that could stock the racks of Barney’s, The French Connection, J.Crew and Urban Outfitters. With nearly limitless design potential, they’re unisex to boot. The fashionistas, the metrosexuals, the bling crowd and just about everyone in-between could get in on the action. And I could wear one, too — joining the caped ranks of the stylish, the hip and the cool — all the while secretly pretending to be Superman.
