With one long sleeve, this one-shoulder evening gown has rows and rows of sequins from the asymmetrical neckline to the floor for a dazzling look at prom, fancy formals, and galas. The figure-flattering long-sleeve formal dress smooths over the curves before flowing to the floor to complete the look. Offered in misses and some plus sizes, this statement-making long sequin prom dress is the definition of sparkly perfection.
