Have you mastered the art of cocktail dressing? If not, The Rhode Island School of Design's Museum of Art wants to show you the way via a new fashion exhibit: “Cocktail Culture: Ritual and Invention in American Fashion 1920-1980.” Running from April 15th to July 31st, the show highlights the art of entertaining—and the chic style that goes along with it! Cocktail Culture boasts over 220 party-ready designs from icons like Christian Dior, Chanel, Balenciaga and Halston. Who said museums were boring? Click through the gallery to view the vintage stunners, or better yet, pay a visit to Providence this weekend to see them in person!
