Product Details
What's Included
- Halter Top Bikini (stretch material)
- Pants with Swimmable Tail (zip on the side)
- Black Monofin
Childrens mermaid tails don't get more vibrant than this 3-piece rainbow swimming costume. The halter bikini top pairs with stretch pants that form a swimmable mermaid silhouette, finished with a dramatically flared tail fin and included monofin.
The scale-pattern fabric features a shimmery gradient that transitions from hot pink at the waist through purple, cyan, and back to pink at the fin. The tail's multi-point striped panels create movement in water. Textured scale embossing throughout gives authentic underwater detail.
Key Features
- Halter-neck bikini top with double-tier ruffle detail and secure tie closure
- High-waisted tail pants with elasticized waistband for comfortable fit
- Side zipper on tail section — slip monofin in before zipping closed
- Soft reinforced monofin insert labeled anti-breaking for pool safety
- Rainbow gradient dye creates seamless color transitions across all pieces

Frequently Asked Questions
What size monofin is included?
The monofin is a soft one-size insert designed to fit girls' feet comfortably. The side zipper allows adjustment for secure wearing during swimming.
Can she swim properly with the monofin?
Yes — the monofin is designed for swimming, but adult supervision is essential. The fin restricts leg movement to a dolphin kick, so ensure she's confident in water before wearing.
How does the side zipper work?
Insert both feet into the monofin first, then slide the tail pants over legs and zip the side closure. This design allows the monofin to stay in place while wearing.
