It’s time for a little reflection on your clothing choices. Specifically, your pants: The metallic leggings currently dazzling Fashion Week regulars are bright enough for sunglasses. Douglas Hannant gilded his model’s gams with ankle-length apparel. Matthew Williamson went for a silver leg (though the Fug Girls couldn’t see anything “Posh” about it). Diesel fueled the craze by contrasting black tops with gleaming gold bottoms. Now you have both the petal and the metal.
