Did you even go on a tropical vacation if you don't have pictures of you posing in a colorful dress against a beautiful backdrop to prove it? A style you'll love to show off on Instagram, Diane von Furstenberg's 'Bethany' maxi design is made from fluid silk crepe de chine and has a vivid floral motif. It's cut in a loose, flowy silhouette and has drawstrings along the waist and cuffs to define your figure.
