A sweeping cami maxi silhouette gives this festival dress instant after-dark energy, shaped with a U neckline, beaded detailing, a daring backless cut and a leg-baring slit. The slim straps keep it effortless while the open back brings that rave-to-rooftop attitude, perfect for dancing under lights or making a date-night entrance. Style it with chunky boots for a tougher festival finish.
