A halter maxi dress with a plunging V neckline that drops to a gathered knot at the waist, where the fabric ruches into a twist before falling into a floor-length skirt with a thigh-high side slit. The back is fully open from the shoulders down, so the ruched waist detail is the only structure holding the silhouette together, and it does double duty as the point that keeps the dress sitting close through the midsection rather than floating loose. The lightweight jersey skims rather than clings through the hip, letting the slit swing open naturally as you walk instead of catching on the leg. It's built for a warm-weather evening — pool party, beach club, or anywhere you'd wear heels and want the fabric to move with you rather than against you.
