This modern iridescent prom dress features many swirling cutouts along the bodice. Although the bateau neckline brings a flare of modesty, the open back looks amazing. Iridescent beading, opal stones, and white sequins swirl along the front and back of the bodice and lead down toward the high-leg slit. With a little more elegance added to the prom dress, a soft chiffon overlay skirt drapes into a sweep train.
