Perfect For
Mermaid-Themed Birthday Parties: The full three-piece set works for under-the-sea birthday parties, aquarium visits, or any event where the birthday girl wants to channel ocean royalty with functional swim gear that doubles as fancy dress.
Book Week & Dress-Up: Bring fairy tale mermaids to life for Book Week parades, storybook character days, or Halloween costume events. The removable tail means she can wear it all day without restricting movement during school activities.
How to Wear It
Tie halter straps snugly at neck and back, ensuring bikini top sits flat. For mermaid mode, zip tail skirt over bikini bottoms and insert monofin into fin pocket. Pair with loose beachy waves, seashell hair clips, or a tiara for the full underwater princess effect.
Frequently Asked Questions
Q1: Can she swim with the tail on?
Yes, the included monofin allows swimming propulsion when the tail is worn. Adult supervision required — the tail restricts leg movement, so it's designed for confident swimmers in controlled environments. Remove tail for independent active swimming.
Q2: What's included vs. sold separately?
The set includes halter bikini top, high-waisted bottoms, zip-on mermaid tail, and black monofin. Hair accessories, jewellery, and cover-ups are not included. The bikini and tail both function independently.
Q3: Is this suitable for Book Week as a fairy tale character?
Yes — the mermaid princess theme fits fairy tale and storybook categories. She can wear just the bikini during active school hours and add the tail for parades or photo opportunities without needing a full costume change.
