Girls Rash Guard Swimsuit – Long Sleeve One-Piece
Size Guide
Use this guide to choose the right size. Measurements are approximate and can vary slightly between styles, so always check the size notes on each product page. If your child is between sizes, we recommend sizing up.
How to measure
- Height: stand your child against a wall without shoes and measure from the floor to the top of the head.
- Weight: use a recent weight; for babies, weight is often the better guide.
- Feet: have your child stand on paper, mark the heel and longest toe, and measure the distance. Add about 1 cm (0.4 in) of growing room.
Some products are labeled by height in centimeters (for example 90cm). That size fits a child who is about that tall.

Why parents love it
A Girls Rash Guard Swimsuit Built for Sun-Soaked Pool Days
Beach days and pool afternoons run long, and bare little shoulders don't hold up to hours of sun. This girls rash guard swimsuit solves that with long sleeves, a comfortable front zipper, and a playful ruffle hem, so kids can swim, splash, and play from morning until the last dip without a swim shirt layered on top. It's a one-piece that does double duty as sun cover and swimwear.
Why Parents Love This Girls Rash Guard Swimsuit
- Long-sleeve sun coverage: Full-length sleeves cover the arms during extended outdoor swim time.
- Easy front-zip design: A smooth front zipper makes getting a wiggly toddler in and out of a wet swimsuit fast and fuss-free.
- Nylon-cotton blend fabric: A soft, stretchy nylon/cotton mix moves with active kids while resisting sagging after repeated pool and ocean use.
- Playful ruffle hem: A ruffled leg trim adds a feminine, boutique-style detail without feeling bulky.
Designed for Real Pool and Beach Days
The one-piece silhouette stays put through cannonballs, swim lessons, and sandcastle building, while the front zip means no getting stuck halfway through a costume change at the pool bathroom: pool parties and swim lessons, beach vacations and family trips, water parks and splash pads, everyday summer outdoor play, and extra arm coverage.
Available Prints
This swimsuit comes in a rotating set of prints, including a multicolor daisy floral, a red-and-white vintage floral, a warm checkerboard, and a solid pink floral.

Care Instructions
Rinse in cool water after each wear to remove chlorine, salt, and sunscreen residue. Hand wash or gentle machine wash cold. Lay flat or hang to dry; avoid high heat.
FAQs
Does the long sleeve design actually help with sun protection?
It adds fabric coverage over the arms versus a sleeveless suit, so treat it as a coverage layer alongside sunscreen.
What sizes are available?
90 (about 1-2 years) through 130 (about 5-6 years).
How does the zipper work?
A front zipper runs from the chest down for quick on/off, even over a wet or squirming toddler.
Will the print fade in chlorine or saltwater?
Rinsing after each swim and avoiding high-heat drying helps preserve the print and fabric.
