Make sunny swim days feel like mermaid adventures
Skip exposed shoulders and outfit fuss with a colorful one-piece that brings playful mermaid style and comfortable long-sleeve coverage to every water day.
Coverage She Wants To Wear

Long-Sleeve Coverage
Long sleeves and a high neckline cover more of the shoulders, arms, and upper chest than a basic swimsuit. Sunscreen and shade are still essential, but fewer areas are left exposed.

Mermaid Style She Loves
The colorful shimmering scale print and coordinated pastel paneling make coverage feel like part of the fantasy, not a compromise. It brings instant personality to pool and beach photos.

One-Piece Simplicity
The fitted one-piece joins the top and shorts-length legs into one coordinated outfit, reducing loose pieces and matching decisions. The smooth stretch fabric keeps movement comfortable.
Front Zip Access
The front quarter-zip gives parents and children a clear opening for getting dressed. Align it smoothly and zip gently, especially when the suit is wet.
Zip In, Swim Out
- 1Choose The Fit
Use the available garment measurements rather than age alone. Look for a close fit that leaves room for comfortable shoulder, arm, and leg movement.
- 2Open The Front Zip
Unzip the quarter-zip before dressing. Guide the arms through the long sleeves, settle the high neckline, and pull the zipper up without forcing it.
- 3Add Sun Essentials
Apply sunscreen to exposed skin and bring shade, a hat, and regular breaks. The suit adds clothing coverage but does not replace a complete sun-safety routine.
- 4Rinse After Swimming
Rinse the suit with fresh water after pool or beach use, then follow the garment care instructions before storing it for the next swim day.
A Better Answer For Sunny Days
Coverage Without The Compromise
Sunny water days often mean balancing exposed shoulders, extra layers, and a child's wish for something exciting. This suit brings long sleeves and a high neckline into one colorful silhouette, so practical coverage does not have to feel dull.
A Suit She Picks Herself
The shimmering scale print turns a sensible choice into part of the fantasy. Bubblegum pink, aqua, lavender, and turquoise details give her a bright mermaid look she will be happy to put on.
Ready For The Whole Day
The fitted one-piece keeps the top and shorts-length legs together through lessons, pool play, beach outings, and holiday photos. With a front quarter-zip and smooth stretch fabric, getting dressed becomes one clear step instead of a search for matching pieces.
Care For The Shimmer
- Rinse promptly
Rinse with fresh water after pool or beach use.
- Dry gently
Follow the garment care instructions and avoid leaving the suit in harsh direct sun for extended periods.
- Treat the print kindly
Avoid rough surfaces and do not pull across the shimmering scale print.
- Protect the zipper
Align the front smoothly and never force the closure.

Questions and answers
No certified UPF rating is provided. The long sleeves and high neckline cover more exposed skin than a basic swimsuit, but the suit must be paired with sunscreen, shade, hats, and sensible sun breaks.
Yes. Apply sunscreen to all exposed skin and use shade whenever possible. Clothing coverage is one part of a complete sun-smart routine.
It gives a clear front opening for dressing, though younger children may need a little practice. Align the zipper smoothly and never force it when the fabric is twisted.
The fitted one-piece keeps the top and shorts-length legs together while smooth stretch fabric supports movement. Check the shoulders, neckline, and legs before class to make sure the fit feels comfortable.
The suit is already a long-sleeve one-piece. A rash guard may feel bulky underneath, so check the fit carefully. For a child using a swim diaper, choose a size that allows comfortable room without sagging.
Use the garment measurements and compare them with your child's height and proportions. Choose a close fit that allows shoulder, arm, and leg movement rather than relying on age alone.
