"Feel like a woman—wear a dress" was the inscription on the tickets attached to Diane von Furstenberg's famous wrap dresses in the early '70s. Twenty years later, the designer's philosophy of "simple, one-step dressing" still rings true--women need elegant outfits that work in virtually any situation, day or night. This time around, von Furstenberg presented her collection in the form of a tableau vivant, with models casually chatting and dancing to the music as guests ambled by. Silk jersey dresses in harlequin prints, paperweight suede numbers in brown, ivy green and pumpkin and double-faced satin sheaths in marble blue and yellow were at the heart of the collection. The silhouette was slinky, seductive and classic, with a distinctly aloof and sophisticated edge.
