Tropical motifs are given a sophisticated slant for Resort 2018, as illustrated by this Oscar de la Renta dark-green and white evening gown. It's tailored in the USA to a strapless silhouette with an internally boned bodice to define the waist and shaped with gathers across the back, then falls into a fully lined skirt that's detailed with a banana leaf-jacquard pattern. Save it for a special occasion, styled with molten metallic heels.
