Girls Mermaid Swimsuit Costume with Swimmable Tail - 3-Piece Bikini Set

What's Included

• Halter-neck bikini top with three-tiered ruffle detailing and adjustable tie closure
• Mid-rise swim briefs with gradient scale pattern and elastic waistband
• Full-length mermaid tail with side zipper and fluke fin (legs-together style for swimming)
• Black monofin insert for tail fin pocket

The Girls Mermaid Swimsuit Costume is a three-piece swimming set combining a wearable bikini with a swimmable mermaid tail. Designed for pool parties, beach days and mermaid-themed events where kids want the full underwater fantasy look.

The gradient colour scheme flows from turquoise at the tail fluke through peach and cream mid-tones to pink-fuchsia at the waist and bikini top. The entire set features raised diamond-scale embossing on metallic-sheen lycra swimsuit fabric — no printed pattern, the texture is molded in. The halter top has three tiers of ruffles creating a layered scale effect; the tail fin shows realistic ridged rays and a dramatic fluke silhouette.

Key Features

• Side zipper on tail for easy step-in and secure closure while swimming
• Monofin insert slides into tail fin pocket for swimming propulsion
• Halter tie adjusts for comfortable fit across different torso lengths
• Heat-embossed scale texture throughout all three pieces resists fading and chlorine wear
• Bikini can be worn separately without the tail as regular swimwear

Perfect For

Pool Parties & Beach Days: Whether it's a backyard pool birthday, resort kids' club mermaid afternoon, or beach photoshoot session.

Themed Dress-Up Events: Book Week fairy tale themes, mermaid birthday parties, underwater fantasy dress days, aquatic character events or fancy dress gatherings with a sea creature twist.

Halloween Costumes & Cosplay: Standalone mermaid look for trick-or-treat events near water, costume parades, or dress-up play at home where kids can swim in character.

How to Wear It

Wear the bikini top and briefs on their own for regular swimming, or add the tail with monofin for mermaid mode. The monofin stays secure in the tail pocket — no need to remove it between uses. Style with a flower crown or seashell hair clips for tropical mermaid princess photos.

Frequently Asked Questions

Care: Hand wash cold, air dry flat, remove monofin before washing.
