At Friday's late-night show, Donna Karan's diffusion line, DKNY, celebrated "the first ten years, the first New York store, the first fragrance and the first season of the millennium." Indeed, with Boy George spinning the background music and a bevy of celebrities in attendance, the show reeled with festive energy. Karan kept the upbeat feeling both on and off the runway: Boys and girls strutted confidently down the catwalk in flesh-colored suede and leather, orange and acid-green nylon, and snake-embossed prints. For her finale, Karan showed a series of metallic denim pieces that sent the audience out—to her party—with a bang.
