Hoodies are no londer just for working out, and sweaters have long since shed the Mr. Rogers image. Light-weight cashmere and silk blends are luxurious enough to pair with boots for a modern, savvy look, but hoods and pouch pockets lend an unexpected casual air. Pullovers and cardigans never go out of style, and today's brands have you looking more like fashionista than revenge of the nerds. Chunky cable knits warm you up even better than that steamy hot chocoloate (and are less fattening), while sheer gauze fabrics keep you cool on summer nights. Tunic lengths are all the rage, perfect when paired with tights, or for a bolder look, worn as a dress.
