Inspired by Fin Fun’s royal Mermaidens from the seven sea kingdoms, who each have a unique story to tell, these fabric mermaid tails feature captivating colors in a realistic mermaid-scale pattern! Every shade of the rainbow projects an unforgettable, three-dimensional look—especially when wet! Fin Fun’s fabric tails are made of premium swimsuit fabric that stretches four ways for a comfortable mermaiding experience. Plus, they’re fade-resistant to sun, chlorine, and saltwater exposure.

Care & Materials

Washing your mermaid tail couldn’t be easier! Just toss it into the washing machine on the cold, gentle cycle—then lay flat or hang to dry. Made of 82% Polyester/18% Spandex.

Care Instructions

Caring for your mermaid tail is easy! Machine wash on the cold, gentle cycle—then hang or lay flat to dry. Avoid high temperatures found in hot tubs and saunas, as this can damage the elasticity of the swimsuit fibers.
