Andrew Gn's black and white polka-dot print gown puts a graphic, pop art-inflected spin on a chic 1960s-esque evening silhouette. It's crafted in France from lightweight silk-crepe with a modern half zip at the high front neckline and elegant bracelet-length balloon sleeves. For a presence that draws all eyes, style it simply with an unobtrusive clutch and lift the floor-sweeping hem with high heels.
