Swimwear
From first cannonballs to backyard sprinkler shows, our girls swimwear is made for movement, mess, and magic. In sizes 2–10, every swimsuit is built for little leaps and big splashes—soft on skin, stretchy for cartwheels, and colorful enough to spot from the snack line. We’re here for beach days, pool parties, lake weekends, and those “one more swim?” moments. Your kid is the captain of the splash squad; we just make the gear that keeps up.
Make a Splash with Girls Swimsuits and Bikinis
Meet the suits that turn pool days into play days. Our girls swimwear range in sizes 2–10 covers all the bases—girls bikini sets for sun-chasing mermaids, one piece swimsuit styles for cannonball confidence, and mix-and-match separates so she can build her own swim story. Think bright, beachy color, playful patterns, and floral prints that bloom even bigger under sunshine. Every style is made to move with her, from jump-in-fast zips on rash tops to comfy waistbands on swim bottoms that don’t roll or pinch.
For the kid who lives in the deep end, one piece suits offer streamlined comfort and secure coverage that stays put during flips, slides, and noodle jousts. For the mix-master, girls bikini sets and tank-style tops let her play stylist—pairing bold stripes with a floral bottom, or a printed top with a solid short. Rash guards and long-sleeve swim tops are the trusty sidekicks for extra sun coverage during those long, splashy afternoons. And because we know the American summer stretches from coast to coast, our kids swimwear is designed for all the places water happens—from Atlantic waves to Pacific tide pools, splash pads in the city, and that blow-up pool in your backyard.
Parents, we see you packing towels, snacks, sunscreen, and optimism. We’ve got your back with soft linings, comfy straps, and easy-wear details that make getting dressed simple and keep the good times rolling. The goal is joy, style, and comfort—without the wiggles or the wedgies—so she can be the hero of every poolside adventure.
Is it better to size up or down in bathing suits?
Short answer: aim true to size for ages 2–10, and let the suit hug—not squeeze—them. Swimwear should feel snug when dry so it fits just right in the water. If a swimsuit starts roomy, it can loosen more when wet, which means slipping straps, gaping necklines, and the classic post-cannonball tug. If it’s too tight, it’ll dig, rub, and cut playtime short.
Here’s a parent-friendly way to check fit without any drama. Have your kiddo reach up high, squat low, and do a little wiggle. Straps should stay put. The bum should stay covered. No digging at the shoulders, no bunching at the tummy. If your child has a longer torso, a one piece may feel short; that’s when sizing up or choosing a two-piece can help. Adjustable straps or tie details are great for in-between sizes, giving you a little extra room without going too big.
For rash guards and swim tops, you can size up if you’re hoping for longer wear, but keep sleeves slim enough that they don’t balloon in the water. And if you’re ever torn between two sizes, pick the one that fits best today; summer doesn’t wait, and comfort wins. When in doubt, check our size guide for measurements tailored to sizes 2–10, and remember that a good fit means more fun and fewer fidgets.
Can kids swimsuits be washed in the washing machine?
Most kids swimsuits can handle a gentle spin, but a quick rinse right after swim time is the real magic trick. Rinsing with cool tap water helps remove chlorine, salt, and sunscreen—saving those bright colors and floral prints for more sunny days. When it’s wash day, use a cold, delicate cycle and pop suits into a laundry bag to protect straps and fabric. Skip bleach and fabric softener; they’re tough on stretch and can fade prints. After the wash, lay flat or hang dry in the shade. The dryer is a no-go—heat can break down elasticity faster than a cannonball splash.
Got sunscreen marks? Rinse first, then use a gentle, swim-safe detergent. Avoid rough pool edges and sitting on concrete—those surfaces can snag fabric and wear out seat panels. A small wet bag in your tote keeps damp suits from mingling with snacks and makes the ride home easier. And as always, peek at the care label before washing. A little care keeps every swimsuit—from the ruffle-trimmed one piece to her favorite girls bikini—ready for the next round of giggles and goggles.
From floral daydreams to rainbow splash zones, Cotton On Kids girls swimwear in sizes 2–10 is built for real-life parenting and real-big play. Soft, secure, and splash-tested by the most honest critics around—kids. Pack the snacks, load the towels, and let her lead the way. We’ll bring the swimwear; she’ll bring the magic.
