Girls Mermaid Swimsuit 3-Piece Set with Swimmable Tail & Monofin

What's Included

• Halter-neck bikini top in hot pink metallic scale-print spandex with ruffled tiers and tie closures at neck and back
• High-waisted bikini bottoms in matching hot pink scale fabric with elastic waistband
• Full-coverage swimmable mermaid tail with gradient ombre (blue-purple-pink) scale print, side zip entry and wide fluke fin
• Integrated black monofin sewn into tail fluke for swimming propulsion

The Girls Mermaid Swimsuit 3-Piece Set combines a metallic-scale bikini with a gradient ombre tail that shifts from ocean blue through purple to hot pink.

The halter top features tiered ruffles and adjustable ties; the high-waisted bottoms offer full coverage. The tail's side zipper runs vertically for quick entry, and the integrated monofin provides real swim propulsion. Scale-print texture across all pieces creates a cohesive underwater-princess look. Wear the bikini alone for regular swimming or add the tail for mermaid transformation at pool parties and beach play.

Key Features

• Dual-wear design: bikini set functions independently or pairs with tail for full mermaid effect
• Swimmable tail with integrated monofin allows actual underwater propulsion (not costume-only)
• Side zipper on tail for easy on/off; no struggling with pull-over entry
• High-sheen metallic scale print across all pieces; gradient ombre tail for realistic ocean-creature effect
• Secure fit: halter ties prevent slippage; elastic waistband on bottoms locks in place during active swim

Perfect For

Pool Parties & Birthday Celebrations: Ideal for mermaid-themed birthday parties, pool deck dress-up, and underwater photo shoots where the birthday girl wants to swim AND pose.

Beach Play & Summer Holidays: Transitions from sand castle building (wear bikini alone) to wave riding in full mermaid tail; compact enough to pack for beach holidays and resort pools.

Imaginative Play & Dress-Up Days: Perfect for Book Week sea-creature characters, fairy-tale princess events, and at-home dress-up where the tail doubles as both costume and functional swim gear.

How to Wear It

Slip on the bikini first, then step into the tail and zip up the side. The monofin slides over feet naturally when legs are inside the tail chamber. Pair with a floral crown or shell headband for ocean-princess vibes (accessories sold separately).
