This glamorous mermaid prom dress is crafted from shimmering sequin-embellished fabric, featuring an elegant asymmetric one-shoulder neckline with a single wide strap and a long, flowing draped sash that wraps around the arm. The form-fitting bodice cinches the waist with a twisted front detail, flowing into a figure-hugging mermaid skirt that flares gently at the hem to create a sleek, elongated silhouette. The all-over sequin texture catches light with every movement, adding a luxurious, eye-catching finish to the design.
