In sparkly glitter-sequin tulle, this long prom dress is sure to shine under the lights. From Colette for Mon Cherie, this gorgeous long designer dress, style number CL2019 is fully-lined from the v-neckline to the floor, with a sparkly sequin-glitter overlay that is as eye-catching as it is flattering. The long sequin formal dress has sheer side insets and thin shoulder straps that lead to the deep v-back to add a sexy vibe, while the long skirt smooths over the hips before reaching a dramatic floor length. Certainly red-carpet worthy for prom, fancy galas, and formal balls, this curve-hugging glitter-sequin long prom dress is simply fabulous.
