5. Diane Von Furstenberg Wrap Dress

The Diane von Furstenberg wrap dress is effortlessly chic and endlessly sexy in equal parts. The silhouette has taken on a life of its own since ex-model Diane von Furstenberg first dreamed it up in the early '70s andsaid, “It’s simply one-stop dressing… It works around the clock, travels across the world, and fits all women’s priorities.” Suitable for both the office and the nightclub, the dress enjoyed wild success (in 1975 von Furstenberg was selling 15,000 of them a week) and remains relevant and on-trend many years later.
