The fancy crystals and embroideries of seasons past may have been stripped away, but luxury lives on for fall in vivid fluorescent color. A trend that started on the street, it’s now filtered up to the runway with Michael Kors’ sporty, traffic-cone-orange sweater and fox fur coat, Narciso Rodriguez’s acid-yellow bandage dress and Marc Jacobs’ electric-blue scuba-inspired poncho. A pop of color is all you need to liven up the neutrals in your wardrobe. No cash for flash? Hit the drugstore and pick up some neon lipstick or nail polish instead. Viva the 1980s.
