What's in the Box

• Halter-neck bikini top with three-tier ruffles (turquoise, stretch fabric)
• Matching bikini bottom with scale texture
• Swimmable mermaid tail with side zipper (gradient aqua-purple-pink with holographic finish)
• Removable black monofin

This Kids Mermaid Tail Swimming Costume brings underwater fantasy to the pool with a halter bikini set plus a swimmable tail that actually moves through the water. The gradient tail shifts from deep turquoise at the hips to sunset pink at the waist, finishing with a structured fluke that holds its shape when your child glides.

The bikini top has three-tier ruffles that add volume without bulk, and the whole set features dimensional fish-scale embossing that catches the light. Side zipper on the tail runs hip to thigh for quick changes. The monofin slots into the fluke pocket — remove it for regular swimming or slot it in for full mermaid propulsion. Side pelvic fins in coordinating blue-pink gradient complete the look.

Perfect For

Pool Parties & Beach Days: Wear the bikini set on its own for regular swimming, then slip into the tail for photo time or mermaid play sessions. Tail restricts leg movement so save it for supervised shallow-water fun.

Mermaid-Themed Birthday Parties: The holographic finish and ombré palette make this the standout piece at any underwater-themed celebration. Pair with a flower crown for the full fantasy effect.

Swimming Lessons with Flair: Monofin use builds core strength and leg coordination — some swim schools incorporate mermaid sessions into their programs. Check with your instructor first.

How to Wear It

Start with the bikini set, then step into the tail and zip up the side. Slot the monofin into the fluke pocket when ready to swim — supervise closely as the tail limits kicking freedom. For casual dress-up, skip the monofin and use the tail as a walk-around costume piece.

Parent FAQs

What size should I order?

Check the size chart for bikini measurements (chest, waist, hips). Tail is designed to fit snugly at hips then flare — if your child is between sizes, size up for comfort. Monofin is one-size.

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

The tail is swimmable with the monofin inserted — leg movement is restricted to dolphin kick. Supervise in shallow water until she's confident. For deep-water swimming, stick to the bikini set alone.

How do I wash this? Will the holographic finish hold up in chlorine?

Rinse immediately after pool use to remove chlorine. Hand wash the tail in cool water, lay flat to dry. Bikini pieces can handle gentle machine wash. Holographic finish is durable but prolonged chlorine exposure will dull it over time.

Is this safe for a child who's still learning to swim?

Monofin use requires solid swimming skills and adult supervision — the tail limits independent leg movement. Save the full tail assembly for confident swimmers in shallow areas, or use the bikini set alone for lessons.

Care: Rinse after each use, hand wash tail, gentle machine wash bikini pieces, air dry.
