Poupette St. Barth specializes in getaway-ready attire, like this Agnes dress. This breezy silhouette features a smocked waistband and a maxi skirt, making it just as flattering as it is comfortable. Pack this in your suitcase for a throw-on-and-go style that will look just as chic with sandals and a beach bag as it will with espadrilles and a coordinating clutch.
