Royal Blue Deep V Halter Neck Beaded Lace Applique Mermaid Prom Dress Fully Open Back High Split Sweep Train Formal Gown

Daring, luminous, and impossibly confident — this royal blue halter mermaid gown is pure red-carpet energy from every angle. The deep V halter neckline plunges dramatically at the center front, its edges defined by the same dense bead embroidery and sequin lace appliqués that cover every inch of the gown — swirling floral and vine motifs in glistening royal blue that shimmer and shift with each movement. The back is the ultimate statement: completely open from neckline to lower back, the halter ties behind the neck and leaves the entire back bare in a breathtaking reveal that is modern, bold, and utterly unforgettable. The fitted mermaid skirt wraps every curve with precision before a high front split opens for freedom and drama, and the gown finishes with a graceful sweep train of embellished lace that fans behind with effortless beauty.
