Bold and beautiful, this black and white long prom dress is a designers dream. A modern style, this one-shoulder formal dress is sold exclusively at PromGirl for a glamorous look at prom, military balls, and other black-tie events. The sparkly evening gown features a fully-sequined one-shoulder bodice with asymmetrical neckline and side cut out that wraps around to the back. The sequined white bodice creates a beautiful contrast as it attaches to the black floor-length skirt that smooths over the hips before opening in a side slit. Offered in misses and plus sizes, this black and white long prom dress is as modern as it is polished posh.
