Product Details

✨ Mermaid Scale Fishtail Costume Dress

A mermaid scale fishtail costume dress brings a little underwater fantasy to the party, with a sweeping shape that feels dramatic as soon as you walk in. Across the front, the mermaid scale fishtail costume dress pairs a shimmering scale pattern with a sweetheart-shaped bodice and slim straps, drawing the eye upward before the silhouette flows down. The fitted upper shape gives way to a broad, flared lower skirt, so this mermaid scale fishtail costume dress reads like a mermaid tail without requiring a separate accessory. Step into a Halloween gathering or themed stage event and let the light catch the patterned front while the sweeping hem makes the entrance feel entirely your own.
