One-piece swimsuits for girls – Full coverage, full confidence
Because real sun protection starts with what they wear
At Juillet Juillet, our UV swimsuits for kids are crafted with care, combining serious sun protection, elegant style, and all-day comfort. Designed for active little girls who love to move, jump, swim, and play, our long sleeve swimsuits are as beautiful as they are protective
Designed for active, curious, and confident little girls, these swimsuits follow every splash, jump, and twirl with ease. Whether she's swimming in the sea, running through the sand, or playing under the parasol, she’s protected and effortlessly styled.
Made with UPF 50+ certified technical fabrics, our one-pieces block over 98% of harmful UVA and UVB rays—even when wet. The result? A thoughtful, reassuring layer of defense where sunscreen doesn’t always reach or last.
A safer, smarter approach to sun care
Children’s skin is particularly fragile. Reapplying sunscreen every two hours isn’t always practical, and missed spots happen—especially during play. That’s why our swimsuits use a physical barrier, not chemical coatings.
Protection is built directly into the fabric. Long sleeves, full back and torso coverage, and a high neckline ensure that the most exposed areas stay shielded. And because there are no added chemical treatments, they’re gentle enough for even the most sensitive skin.
The protective effect doesn’t wash out or fade. It lasts—swim after swim, wash after wash—making these pieces an essential part of a child's summer wardrobe.
Designed for comfort, created for movement
Every swimsuit is made to be worn all day, with the kind of softness and flexibility that kids need to feel free. Our fabrics are lightweight, breathable, and quick-drying, ensuring comfort whether wet or dry.
They’re also highly resistant to salt, chlorine, meaning they hold their shape and function throughout the season. No tugging, no sticking, no discomfort—just effortless ease.
Cut with precision and care, these swimsuits offer a silhouette that’s structured yet flexible, modest yet modern. They follow her body, not the other way around.
A playful aesthetic with a timeless French twist
Style is never secondary at Juillet Juillet. Our one-piece swimsuits blend retro elegance with joyful energy, in a palette of bold hues, striped accents, and summery prints.
These are pieces made to be seen as much as they are made to protect. They reflect the spirit of the brand: sun-smart, charming, and quietly confident. Easy to wear, easy to pair, and easy to love—by girls and parents alike.
Whether worn alone or with a coordinated UV hat or short, each swimsuit forms the base of a complete, sun-safe look that doesn’t need to shout to stand out.
In a nutshell
Our one-piece UV swimsuits for girls offer UPF 50+ certified protection, with long sleeves, full torso and back coverage, and breathable, quick-dry performance.
They’re soft on the skin, strong against the sun, and made for a childhood spent outdoors—with confidence and style.
