Purple Strapless Sequin Mermaid Dresses are a must have for women who want to look beautiful during prom or any formal occasion. The strapless sweetheart bodice is covered with purple and black sequins and is adorned with beads around the bust line. We love this gorgeous long purple sequined gown because the mermaid skirt slightly flares out for a chic look. Wear these evening dresses for prom, wedding, formal parties, graduation, homecoming, or for any special event.
