Once the temperature drops and wardrobe options are limited by inclement weather, a sartorially obsessed girl can become frustrated by the limitations of jeans and sweaters. The cure for that impending boredom? The sweaterdress. This winter-wardrobe essential embodies the best of two very stylish worlds: The coziness and versatility of a pullover and the easy-to-wear, feminine power of a dress. Layer it over opaque tights, leggings or a slim-fitting pair of jeans and virtually any boot for a cool (or hot, as it may be) take on a classic cold-weather outfit.
