Girls Swimmable Mermaid Tail Costume with Bikini Set - Purple Gradient

What's Included

• Halter bikini top with bow accent and adjustable tie straps (stretch nylon-spandex blend)
• Swim bottoms with elastic waistband (matches bikini top fabric and gradient)
• Swimmable mermaid tail with side zip closure, raised scale texture, and semi-transparent fluke (purple-pink gradient)
• Black monofin insert for swimming propulsion (fits into integrated tail pocket)

The Girls Swimmable Mermaid Tail Costume transforms pool time into underwater fantasy play with a functional three-piece set featuring a halter bikini, matching swim bottoms, and a zippered scaled tail that genuinely works in water.

The purple-to-pink gradient runs across all three pieces with a tie-dye ombré effect in lavender, peach, and blue tones. The tail body features raised dimensional scales with metallic sheen, finishing in a translucent flared fluke with side hip fins. The halter top ties at the neck and back for adjustable fit, with a centered bow detail. Stretchy nylon-spandex blend ensures comfortable movement both in and out of the tail.

Key Features

• Side zip on tail for quick on/off — no wrestling wet fabric over feet
• Integrated monofin pocket at tail fluke provides real swimming propulsion in the pool
• Elastic waistband on both swim bottoms and tail opening for secure layered fit
• Raised scale texture and gradient dye create dimensional underwater-princess effect
• Bikini set functions as standalone swimwear when tail is removed — two looks in one

Perfect For

Pool Parties & Beach Days: Wear as a regular bikini set for swimming laps, then zip on the tail for mermaid-themed games, underwater photos, or fantasy play in the shallows.

Book Week & Dress-Up Events: Classic fairy-tale mermaid theme works for storybook character days at school, princess dress parties, or underwater-themed birthday celebrations.

Costume Swim Events: Mermaid swim lessons, aquatic fancy dress competitions, or synchronised swim clubs where the monofin adds authentic tail propulsion.

How to Wear It

Put on bikini top and bottoms first as base layer. Step into the mermaid tail, pull up over swim bottoms, and zip the side closure. Slide monofin into the integrated pocket at the tail fluke. Add a flower crown or shell hair clips for full underwater-princess styling — keep jewellery waterproof or remove before diving in.
