What's in the Box

Halter bikini top with shell appliqué and tie-back
Mid-rise bikini bottoms
Swimmable mermaid tail with integrated fluke fin
Black monofin for dolphin-kick propulsion

This Kids Swimmable Mermaid Costume Set is a genuine functional swimsuit — your child swims in it, not just poses. The turquoise scale-print bikini, slip-on tail, and rigid monofin turn any pool session into an underwater adventure.

The halter bikini top has adjustable tie-back closure for secure fit during swimming. Elasticized tail waist slips on over the bikini bottoms, and the monofin inserts into the fluke for dolphin-kick propulsion. Long vertical fringe strips on the fin create realistic flowing movement underwater. Digitally printed black-outlined scales cover all pieces for dimensional aquatic effect.

Perfect For

Mermaid Pool Parties & Beach Days: The standout piece for underwater-themed birthday parties, summer beach outings, or resort pool sessions where your kid wants to live the mermaid fantasy for real.

School Dress-Up & Book Week Costumes: Pairs with any ocean mythology book for Book Week — storybook mermaid parades, underwater character days, or school swimming carnivals with a costume theme.

Everyday Imaginative Swim Play: Doubles as regular swimwear for kids who want to be a mermaid every time they hit the water — backyard pool, local aquatic centre, or holiday beach swimming.

How to Wear It

Slip the bikini on first, then slide the tail over the bottoms and position the monofin inside the fluke. Secure the halter tie snugly. Pair with a swim cap or let hair flow loose for full mermaid effect — skip goggles if your child is confident underwater.

Parent FAQs

Q: What size should I order?

A: Check the size chart for chest and waist measurements. The tail has elasticized waist for flex, but the monofin fit is more specific — between sizes, go up for growing room.

Q: Can they really swim in this, or is it just for photos?

A: They can genuinely swim. The monofin provides propulsion for dolphin kicks, and the tail fabric allows leg movement. Supervise closely — swimming with a monofin takes practice and isn't suitable for beginners or non-swimmers.

Q: How do I wash this? Will the print fade?

A: Rinse in fresh water after pool or beach use to remove chlorine and salt. Hand wash cold, line dry in shade. The digitally printed scale pattern is durable but avoid harsh detergents.

Q: Is this safe for my child to wear in the pool?

A: It's designed for swimming, but monofin use requires confident swimming ability and adult supervision. Not recommended for shallow water, non-swimmers, or children under 6 without strong swim skills.

Care: Rinse after use, hand wash cold, line dry in shade.
