What's in the Box

Halter-style bikini top (rainbow gradient scale print)
Elasticated brief bottoms (matching scale pattern)
Full swimmable mermaid tail with side zipper
Detachable black monofin insert (anti-breaking construction)

This Girls Rainbow Mermaid Swimsuit turns pool parties into a fairytale moment. The three-piece set includes a halter bikini, matching briefs, and a full-length mermaid tail with a detachable monofin — your child can swim like a real mermaid or wear the bikini on its own.

The rainbow gradient flows from pink through purple to blue-green with an embossed scale texture across every panel. The tail features wing-like pectoral fins, a pleated fluke with glitter accents, and a side zipper for easy on/off. The monofin slots into the tail's internal pocket and stays secure during underwater play. Metallic holographic finish catches the light beautifully for photos.

Perfect For

Pool Parties & Beach Days: A showstopper for summer birthday parties, resort holidays, or afternoon swims at the local pool — pairs with goggles and floaties for a full mermaid experience.

Mermaid Dress-Up Play: Works for imaginative play at home, kindy mermaid dress-up days, or aquatic-themed school events — the tail zips off when it's time to run around on land.

Photo Shoots & Special Occasions: Stunning for underwater photography sessions, beach family portraits, or costume parades where she wants to stand out in shimmering rainbow scales.

How to Wear It

Slip on the bikini first, then step into the tail and zip it up the side. Slide the monofin into the tail's internal pocket at the fluke end for swimming propulsion. For play outside the water, remove the monofin and wear the tail as a walk-around costume piece.

Parent FAQs

Q: What size should I order?

A: Check the size chart for chest and waist measurements. The bikini top has some stretch; the tail's waistband is elasticated so it sits comfortably at the hips. If your child is between sizes, size up for room to grow.

Q: Can she actually swim in this, or is it just for dress-up?

A: She can swim with the monofin attached — the tail is designed for pool use. Supervise closely as the monofin changes how she moves through the water, and make sure she's confident swimming before trying the tail in deep water.

Q: How do I wash this? Will the holographic finish peel?

A: Hand wash in cold water and lay flat to dry. The metallic finish is printed onto the fabric, but chlorine and rough handling will dull it over time. Rinse thoroughly after each pool session to keep the shimmer bright.

Q: Can she wear the bikini without the tail?

A: Absolutely — the halter top and briefs work as a regular swimsuit. The tail detaches completely via the side zipper, so she can switch between mermaid mode and normal swimming depending on the activity.

Care: Hand wash cold, rinse after pool use, lay flat to dry. Avoid wringing or tumble drying.
