Festival fields, neon-lit raves and late-night dance floors call for a top that keeps the energy high. This solid halter top frames the neckline with a sleek U shape, while the backless cut brings that bold, barely-there attitude made for warm nights and spotlight moments. Clean, minimal and easy to wear, it lets the silhouette do the talking. Style it with low-rise cargo trousers for an effortless festival outfit.
