PRODUCT DETAILS
What's in the Box
- Halter-neck bikini top with tiered ruffle detail
- Matching swim briefs with gradient scale pattern
- Full-length mermaid tail with side zipper
- Black monofin insert for swimming
This Kids Mermaid Swimsuit with Tail turns pool time into a proper underwater adventure. The turquoise-to-pink gradient shifts from tropical aqua at the tail fin through peachy coral to fuchsia at the waist — like she's swum straight out of a reef.
All three pieces feature textured raised scales with a metallic sheen, the kind that catches the light when she surfaces. The halter top has three tiers of ruffles for a layered fin effect, and the tail's got realistic ridges on the fluke. Side zipper means she steps in and zips up — no wrestling into it wet. The monofin slides into a pocket at the tail base so she can actually swim (not just pose for photos, though it's excellent for that too).
Perfect For
Pool Parties & Beach Days: A standout at kids' pool parties, resort splash zones, or beach photoshoots — pairs with a flower crown for full tropical mermaid princess energy.
Book Week & Fairytale Dress-Up: Natural pick for fairytale character parades, underwater fantasy themes, or any Book Week event where mermaids and mythical sea creatures fit the brief.
Mermaid-Themed Birthdays: The hero outfit for a mermaid birthday party or ocean-themed playdate — she'll be the one all the other kids want to photograph.
How to Wear It
Wear as a regular bikini set (top + briefs) for active swimming, or add the tail with monofin for slower mermaid glides and photo ops. Pair with waterproof hair clips or a floral headband — skip any accessories that could tangle in the zipper.
Parent FAQs
Q: What size should I order?
Check the size chart for chest and waist measurements. The halter tie adjusts for length; if your daughter's between sizes, go up — lycra swimwear has less give than cotton costumes.
Q: Can she actually swim in the tail, or is it just for photos?
She can swim with the monofin inserted — it's designed for slow, dolphin-kick style movement in the pool. Not for deep water or unsupervised use; treat it like any swim aid and stay within arm's reach. Remove the tail for active play or diving.
Q: How do I wash this after chlorine exposure?
Rinse in cool fresh water immediately after pool use to prevent chlorine fade on the gradient dye. Hand wash with mild detergent, lay flat to dry out of direct sun. Don't tumble dry or iron — heat damages the metallic finish.
Q: Is the flower crown included?
No — the crown in the photos is a styling prop. The set includes the bikini top, swim briefs, tail, and monofin only. Pair with your own floral clips or leave her hair loose.
Care: Rinse after pool use, hand wash, lay flat to dry.
