Oscar de la Renta's graceful gown is ticking all of our eveningwear boxes thanks to its floor-grazing length, fluttering cape-like sleeves and a figure-defining adjustable bow detail at the back. Made from a fluid metallic fabric with flecks of silver and gold, it captures a retro type of glamour that we love, which is heightened by bronze-toned glass bead embellishments that form elegant leaf motifs around the neckline. Slip yours on with champagne-toned sandals to complete the look.
