Girls Mermaid Costume Tail Swimsuit Princess Bikini Set

What's in the Box

• Halter-neck bikini top in rainbow ombré with layered ruffles
• Mid-rise bikini bottoms (matching gradient print)
• Zip-side mermaid tail with iridescent scale pattern and triple-point fluke fin
• Black monofin insert for swimming propulsion

This Kids Mermaid Tail Swimsuit Set brings underwater princess dreams to the pool, with a gradient rainbow ombré that shifts from pink through peach, yellow, mint, aqua, blue, and purple — all with a fish-scale texture and holographic shimmer on the tail fin. The halter bikini and bottoms work as a regular two-piece swimsuit; zip on the swimmable tail and slide in the monofin when it's time for fantasy swimming or mermaid photo ops.

Perfect for mermaid-themed birthday parties, pool dress-up days, beach outings, and Book Week fairytale parades. The side zipper on the tail makes getting in and out easy, and the stretchy swimsuit fabric handles chlorine and saltwater without losing its colour.

Parent FAQs

Can she actually swim in the tail?

Yes — the monofin slots into the tail's foot pocket to let her kick dolphin-style. The tail restricts leg movement (that's how mermaids swim), so she needs to be a confident swimmer and have adult supervision in the pool. The side zip lets you take the tail off quickly poolside if she gets tired.

What size should I order?

The halter top and bottoms are stretch swimsuit fabric, so they'll flex a bit. If your child is between sizes, size up — the tail needs to fit snugly at the hips but not restrict breathing. The adjustable halter tie gives you wiggle room through the torso.

Care: Rinse in cool water after each swim to remove chlorine or salt. Hang to dry (don't wring the tail — it damages the fin structure). Hand wash only; no tumble dryer.
