Winter white came early this year . . . and I always welcome it with open arms. Here it is in its diverse glory, on three fabulous females. Diane, dressy, in off-white girlie Chanel. Kate Beckinsale, cozy, in a striped cardigan sweater and cool blanco aviators. Zoe, chic, in cropped white jeans and sharp accompaniments. All ladies offset their pristine powder with black and gray, maintaining a cool aura. So what if it gets dirty — it looks damn good.
