What's in the Box

Halter-neck bikini top with tiered scale ruffle overlay
Bikini brief bottoms with matching scale print
Full-length rainbow mermaid tail with side zipper
Black monofin for swimming propulsion

This Kids Mermaid Swimsuit with Tail brings fairy tale magic to the pool, with a stretchy scale-print bikini and a vibrant rainbow tail that actually swims. The tail's side zipper lets your kid step in and out easily, and the integrated monofin gives them real mermaid-style propulsion through the water.

The bikini top features tiered scalloped ruffles in a pink-to-green ombré gradient, while the tail explodes in magenta, blue, turquoise, yellow, and purple with an iridescent finish. Halter ties adjust for a secure fit, and the stretchy swim fabric moves with them whether they're splashing at the shallow end or practising their dolphin kick.

Perfect For

Pool Parties & Beach Play: A showstopper for summer birthday swims, mermaid-themed pool days, or any beach trip where your kid wants to make a splash.

Book Week & School Dress-Up: A natural pick for fairy tale character parades, under-the-sea literature themes, or any storybook day where mermaids and ocean fantasy fit the brief.

Costume Swim Lessons & Dress-Up Swim: Doubles as functional swimwear for costume swim sessions, aquatic centres' themed days, or just backyard pool fun with a magical twist.

How to Wear It

Slip into the bikini first, then step into the tail through the side zipper opening — the monofin stays attached at the fluke end. Pull the zipper up along the leg and you're ready to swim. Pair with a beach towel cape for the walk to the pool, or add a shell necklace for full mermaid energy.

Parent FAQs

Q: What size should I order?

A: Check the size chart for height and chest measurements. The bikini is stretchy swim fabric so it has some give, but the tail length matters most — you want the monofin to sit comfortably at foot level without excess fabric bunching.

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

A: She can genuinely swim — the monofin is rigid plastic designed for propulsion, and the tail fabric is swim-grade material. That said, supervise closely and make sure she's confident in the water; swimming with a monofin takes practice and isn't suitable for beginners or non-swimmers.

Q: How do I wash this? Can the monofin go in the machine?

A: Hand-wash the tail in cool water and lay flat to dry — the monofin component makes machine-washing risky (could damage both washer and fin). The bikini pieces can go in a delicates bag on gentle cycle, but rinse chlorine out promptly after each pool session to keep the colors bright.

Q: Is this suitable for Book Week if the school allows swimwear costumes?

A: Absolutely — mermaids are classic fairy tale and storybook characters, so it ticks the literature box. Just confirm your school's dress code allows swimwear-as-costume; some kindy and primary classrooms prefer over-clothes costumes for indoor activities.

Care: Hand-wash tail, rinse chlorine after use, lay flat to dry.
