Mermaid Prom Dresses

Shop mermaid prom dresses at ONTOEFY for a dramatic, hourglass silhouette. A fitted bodice hugs the waist and hips before flaring at the knee, creating a red-carpet look for prom photos.

Our collection includes satin and chiffon mermaid gowns with corset bodices, draped details, high slits, and lace-up backs. Choose black, red, burgundy, navy, emerald, and sage. Sizes 2-28, with custom sizing on selected styles.

Explore all prom dresses, corset prom dresses, or ball gown prom dresses.

I’m absolutely in love with my hoco dress! The quality is amazing, the fabric is soft and comfortable, and the fit is perfect. It’s stylish, flattering, and looked stunning at the dance. I got so many compliments all night long. Shipping was fast, and it’s totally worth the price. Highly recommend!
