Valentino’s tailored wool suit ($815), available at selected Neiman-Marcus stores, leaves its familiar daytime haunts to strike at night. It’s all part of the new fall fashion clockworks called a.m./p.m. dressing. The idea is to wear your tweeds at night, your velvets during the day. Tailored and innocent are the big news for after hours; a touch of glitter and sensuality signal power while the sun shines. A fashionable surprise with flattering results. Our cover was photographed by Matthew Rolston, who also captured the striking day-for-night and night-for-day looks in Marylou Luther’s article beginning on Page 8.
