Kids Rainbow Mermaid Tail Costume with Monofin - Swimmable 3-Piece Set

The Kids Rainbow Mermaid Tail Costume is a three-piece swimmable set featuring a halter-neck bikini top with tiered scale-print flounces, matching briefs, and a full-length rainbow gradient mermaid tail with integrated monofin. The vibrant multi-colour ombré effect transitions from aqua and blue at the waist through purple and pink to the fluke, creating the modern "unicorn mermaid" look popular at pool parties and beach holidays.

The halter top features three scalloped ruffled layers that mimic fish scales, finished with rainbow gradient neck ties. The stretch polyester tail has a convenient side zipper for easy on/off and a bottom sleeve that holds the included black monofin, allowing genuine swimming propulsion. Sculptural side fins and a multi-pointed fluke with iridescent detailing hold their shape in water, completing the fantasy ocean princess silhouette.
