One-Shoulder Royal Blue Mermaid Prom Dress with Sparkling Sequins

Make an entrance you will remember in this blue one-shoulder mermaid prom dress. Sequin-covered cups sit above a ruched bodice and a fitted waist, then the skirt falls into a long sweep train that moves beautifully as you walk. It keeps you comfortable through dinner and dancing while still looking polished in every photo.
