Kids Mermaid Tail Costume - Swimmable Bikini Set with Monofin

What's in the Box

• Halter-neck bikini top with bow detail and ruffle trim
• Matching bikini bottom with scale texture
• Fitted mermaid tail with side zipper
• Black monofin for swimming propulsion

This Kids Mermaid Tail Costume turns pool parties into underwater adventures with a swimmable three-piece set sized for primary-age girls. Hot pink and turquoise gradient with embossed scale texture, translucent fin panels, and a removable monofin that slots into the tail through a side zip.

The halter bikini top ties at the neck for adjustable fit, paired with a matching scale-print bikini bottom that wears under the tail. Stretch lycra throughout moves with your child in the water. Side zip on the tail means the monofin comes out in seconds if she needs to kick free and swim normally — practical for swim-confident kids who want the mermaid glide without compromising safety.

Perfect For

Pool Parties & Beach Play: A showstopper for mermaid-themed birthday parties, resort holidays, or backyard pool sessions where she can practice dolphin kicks and make a splash.

Dress-Up & Imaginative Play: Works just as well on dry land for princess dress-up, storybook character parades, or casual mermaid role-play at home.

Book Week & School Dress-Up Days: Pairs with any underwater storybook character — The Little Mermaid tales, ocean adventure picture books, or fairytale sea princess themes.

How to Wear It

Slip on the bikini set first, then slide into the tail and zip up the side. Insert the monofin through the pocket opening and zip closed. She can walk short distances on dry pool decking (shuffle steps, not running), then glide through the water with both legs together in a dolphin kick. To remove quickly, unzip the side and step out — the bikini bottom stays on underneath.

Parent FAQs

Q: What size should I order?

A: Check the size chart image for chest and height measurements. The bikini top has adjustable halter ties, and the tail's stretch fabric gives some flex, but length matters — too short and she'll outgrow it fast, too long and the fins drag on the pool floor.

Q: Is this safe for swimming?

A: The tail is swimmable with the monofin, designed for swim-confident kids who can dolphin-kick and hold their breath underwater. The side zip allows quick release if she needs to switch to normal leg kicks. Always supervise in the water — mermaid tails restrict leg movement and aren't suitable for non-swimmers or deep water without adult oversight.

Q: How do I wash this? Is the fabric durable?

A: Rinse in cool fresh water after each pool or beach session to remove chlorine and salt, then air-dry flat. Hand-wash gently when needed. The lycra blend holds up to regular swim use, but the scale texture can fade with harsh detergents or tumble-drying.

Q: Can she wear this for Book Week?

A: Yes — it's perfect for storybook mermaid or ocean character dress-up. Just note that most schools won't let her wear the full tail with monofin to class (trip hazard on dry land). She can wear the bikini set with the tail unzipped and draped over her legs for the look, then save the full swimming setup for pool parties.

Care: Rinse after swim use, hand-wash gently, air-dry flat. No tumble dryer.
