At the festival, this slit flower appliqué backless tube maxi dress brings floaty drama with a bare-shoulder neckline, open back and leg-flashing cut that moves beautifully from golden hour to the afterparty. The floral detail adds a romantic hit while the maxi length keeps the look sleek, bold and camera-ready for rave fields, beach stages or a summer night out. Style it with strappy heels for a polished going-out finish.
