What's in the Box

Halter bikini top with tie closure
Matching bikini bottoms
Swimmable mermaid tail with scale print
Black monofin for propulsion

This Kids Mermaid Tail Swimsuit turns pool time into an underwater fantasy, with a fitted pink mermaid tail, matching halter bikini and a proper monofin for real swimming. The scale pattern runs coral-to-blush across stretchy swim fabric, ending in a flowing translucent fin that catches the light.

The tail isn't just for show — it has an internal pocket at the foot end where the monofin slots in, so your child can actually propel through the water. The bikini top ties at the neck with a metallic emblem at the centre; bottoms have standard swim-brief elastic for secure fit. Fabric is Lycra-blend swimwear that holds its shape wet or dry.

Perfect For

Pool Parties & Beach Days: The standout costume for any mermaid-themed birthday party, backyard pool session, or beach holiday where your kid wants to make a splash.

Swim Lessons with Flair: Adds fantasy element to swim practice while the monofin builds leg strength and teaches dolphin-kick technique — instructors often approve these for confident swimmers.

Water Park Visits & Casual Dress-Up: Works as a functional swimsuit at water parks (check facility rules on monofins first) or for dress-up play on dry land when the tail's on but the fin's out.

How to Wear It

Put the bikini on first, then step into the tail and pull it up to the waist. Slide both feet into the monofin pocket at the tail's end — feet stay together, like a dolphin kick. Practice in shallow water first until your child gets the rhythm.

Parent FAQs

Q: What size should I order?

A: Check the size chart image — it's based on height and waist measurement. The tail fabric has stretch, but you want the waist snug enough to stay put during swimming. If between sizes, go up for growing room.

Q: Is this safe for a beginner swimmer?

A: The monofin restricts individual leg kicks, so this is best for kids who are already confident swimmers and comfortable in deep water. Always supervise, and let them try it in shallow water first to get used to the dolphin-kick motion.

Q: Can they wear this in chlorinated pools?

A: Yes — the Lycra swim fabric and monofin are pool-safe. Rinse in fresh water after each swim and hang to dry. Avoid leaving it bunched up wet, which can fade the print over time.

Q: Does the tail come off easily for bathroom breaks?

A: It's a snug pull-on, so it takes a minute to wriggle out of — not as quick as regular swimmers. Plan bathroom stops before putting it on, or keep a towel nearby for a quick change.

Care: Rinse in cold water after each use, hang to dry. Hand wash if needed, no machine tumble.
