What's in the Box

• Halter-neck bikini top with ruffled tiers and tie closure
• High-waisted bikini bottom (matches top)
• Swimmable mermaid tail with ombre gradient (blue to purple to pink)
• Integrated black monofin for underwater propulsion

This Kids Mermaid Costume Swimsuit turns any pool day into an ocean adventure — hot pink metallic bikini set pairs with a gradient ombre tail that shifts from blue through purple to pink, mimicking real sea-creature scales. Side zipper runs the length of the tail so your child can slip in and out between swims, and the built-in monofin gives them mermaid propulsion for underwater gliding.

The scale-print fabric has high sheen and stretch, comfortable for hours of wear. Halter top ties at neck and back for adjustable fit; high-waisted bottoms sit securely at the waist. Tail tapers down to a wide fluke with decorative hip fins, and the metallic texture catches light beautifully in water. Wear the bikini alone for regular swimming or zip into the tail for mermaid transformation — dual functionality parents love.

Perfect For

Pool Parties & Beach Days: A natural choice for mermaid-themed birthday parties, seaside holidays, or backyard splash days where your child wants to channel underwater magic.

Dress-Up & Imaginative Play: Perfect for kindy mermaid parades, ocean-themed school events, or at-home play where she's an ocean princess exploring coral reefs.

Swimming Lessons with Flair: The monofin teaches dolphin-kick technique while making practice feel like fantasy — great for kids who love costume swimming but need functional swimwear.

How to Wear It

Wear the bikini set first, then step into the tail and zip it up the side. Monofin goes on like a flipper — feet slide into the pocket at the fluke. Pair with a floral crown or starfish hairclip for extra sea-fairy energy (accessories not included). After swimming, unzip the tail and rinse both pieces in fresh water.

Parent FAQs

What size should I order?

Check the size chart for chest and waist measurements — the bikini has stretch but the tail length is fixed per size, so if your child is between sizes and tall, size up for comfort.

Can she actually swim in this, or is it just for photos?

Genuinely swimmable — the monofin is designed for underwater propulsion, and the tail fabric is swimsuit material. Supervise as with any pool toy; the tail restricts leg movement so she'll need to dolphin-kick.

How do I wash this? Will the sheen fade?

Rinse in cool fresh water after each use to remove chlorine or salt. Hand wash gently when needed, hang to dry away from direct sun. The metallic print holds up well with proper care.

Is the monofin removable, or is it sewn in?

The monofin is integrated into the tail fluke — not removable. This keeps it secure during swimming but means the tail must be stored flat or loosely rolled to avoid creasing the fin.

Care: Rinse after each swim, hand wash cold, hang dry, no bleach.
