Kids Swimmable Mermaid Tail Costume - Pink & Blue Gradient Bikini Set with Monofin

What's in the Box

• Hot pink halter bikini top with triple ruffle tiers
• Hot pink bikini bottoms
• Gradient pink-to-blue swimmable mermaid tail with ombré scale print
• Black monofin insert for swimming propulsion

This Kids Swimmable Mermaid Tail Costume turns pool parties and beach days into full fantasy mode, with a vibrant gradient scale tail your child can actually swim in. The halter bikini top features three layers of ruffles and tie closures at neck and back; the tail runs from light blue at the waist through purple mid-section to hot pink at the flared fin, with a removable monofin that fits inside for real underwater mermaid propulsion.

Shimmery holographic scale print catches the light at every angle, and the tail's elasticated waistband keeps it secure even during active swimming. Monofin is separate — slide it into the tail's pocket before your child dives in, or wear the tail on its own for dress-up on dry land. Bikini pieces are fully lined for comfort and coverage.

Perfect For

Pool Parties & Beach Days: A functional swimsuit that doubles as a costume — your child can swim laps, practice mermaid kicks, or lounge by the water looking straight out of a coral reef kingdom.

Book Week & Mermaid Story Dress-Up: Perfect for any mermaid character parade, The Ocean Mermaid events, or ocean-themed school dress-up days where swimming capability isn't needed but the look is.

Birthday Parties & Fantasy Play: Ideal for mermaid-themed birthday celebrations, underwater photoshoots, or weekend dress-up swimming sessions at the local pool or waterpark.

How to Wear It

Put the bikini on first, then step into the tail and pull the waistband up to natural waist. Slide the monofin into the tail's pocket if she's swimming, or skip it for dry-land dress-up. Pair with a beach towel cape and shell necklace for full under-the-sea energy.

Parent FAQs

What size should I order?

Check the size chart for chest and waist measurements. Tail waistband is elasticated so it flexes, but the bikini top needs accurate chest sizing — between sizes, go up for comfort and longer wear.

Can she swim safely with the monofin?

The monofin requires swimming confidence and coordination — she should be a competent swimmer who's comfortable in deep water. Always supervise, and practice in shallow water first before she dives in. Monofin can be removed for easier swimming.

How do I wash this?

Rinse the bikini and tail in fresh water after pool or beach use, then hand-wash in cold water with mild detergent. The monofin wipes clean — don't submerge it in a washing machine.

Is this suitable for Book Week if she's not swimming?

Absolutely — wear the tail over the bikini on dry land for any mermaid character parade or ocean-themed school event. The scale print and gradient colours photograph beautifully even without the water element.

Care: Hand-wash bikini and tail in cold water, air dry. Wipe monofin clean.
