Picking swimwear for little ones isn’t just about cute prints and tiny mermaid tails — it’s about safety, comfort and sun protection. When kids are splashing around, swimwear becomes their first line of defense against UV rays, abrasions from pool decks, and uncomfortable chafing. You want fabrics that dry fast, cuts that stay in place when they run, and UPF-rated garments that block the sun. Think of a good swimsuit like sunscreen with fabric — it’s a wearable shield that lets kids play longer while parents breathe easier.
Not all swimsuits are created equal. Look for UPF ratings (UPF 50 is ideal), flat seams, and features like built-in sun hats or long sleeves for maximum coverage. Stretchy synthetic blends such as nylon-spandex or polyester-spandex offer quick-dry performance and a snug fit that holds up in chlorinated water. Also consider closures—snug snaps and zippers are great for infants because they help with quick changes and prevent the suit from slipping during play.
UPF stands for Ultraviolet Protection Factor. A UPF 50 fabric blocks about 98% of UV radiation, which drastically reduces harmful sun exposure compared to bare skin. For babies under 6 months you should minimize direct sun altogether, but for toddlers and older kids, UPF 50 swimwear adds a reliable layer of protection on top of sunscreen for exposed areas like faces and legs.
Walmart is a go-to for families who want variety and value. Their baby and toddler swimwear selection includes adorable sets like mermaid rashguard suits and practical items such as one-piece dinosaur suits with matching sun hats. Those long-sleeve rashguard sets with UPF 50 are particularly popular because they offer broad coverage at pocket-friendly prices. If you need a quick replacement suit before a weekend beach trip, Walmart’s range — from branded Carter’s options to playful licensed characters — makes it easy to find something that fits both your budget and style preferences.
Walmart combines affordability with convenience. You can find sizes from newborn all the way to toddler and little kid sizes, and many items are machine washable and low-maintenance. The selection often includes coverups and small accessories like bucket hats and swim diapers, making it a one-stop spot for last-minute family swim needs.
Cerqular offers a more curated selection that feels boutique but stays accessible. Their collection often focuses on UV swim sets and stylish patterns — think retro florals, understated solids, and well-tailored swim shorts. For parents who want something a bit different from mass-market prints, Cerqular’s offerings like cream Padma Mundra UV sets or fitted boys’ swim shorts in teal designs are great picks. These pieces often prioritize fabric quality and thoughtful sizing, so the fit tends to be more tailored than generic fast-fashion options.
If you care about unique prints, eco-friendly blends, or a refined fit, boutique-style swimwear is worth the extra spend. These suits often use mid-weight fabrics that hold shape and resist fading, so they can look newer longer than cheaper options. They also make great gifts or special-occasion outfits when you want your child to stand out at family photos or a special beach day.
Beyond Walmart and Cerqular, several other US retailers consistently deliver both style and function for kids’ swimwear. Stores like Old Navy, Target, Carter’s, Gap Kids and Amazon offer broad selections across price points. Each of these shops has strengths: Old Navy for trend-forward basics, Target for stylish collaborations and convenience, Carter’s for baby-first reliable sizing, Gap Kids for higher-quality classics, and Amazon for a gigantic selection and fast shipping.
Old Navy and Target are great when you want up-to-date prints and frequent seasonal drops. Old Navy’s swim line is kid-friendly with popular character prints, and Target often features exclusive designer collabs and budget-friendly UPF options. Both chains typically stock rashguards, bikinis for older kids, and affordable accessories like water shoes and swim goggles.
Carter’s excels at baby sizing and gentle fits that work well for infants and toddlers. Gap Kids leans into softer fabrics and classic silhouettes that families return to season after season. Amazon marketplace variety includes niche brands and international options, which is handy if you’re hunting for specialized fits like long torso one-pieces or swim rompers with snap closures for diaper changes.
Size charts are your best friend. Babies and toddlers grow quickly, so measure chest, waist and length and check the brand’s size chart—sizes labeled 12 months, 18 months, 2T or 4T can vary widely. For infants, opt for one-piece suits with generous room for diapers and easy snap closures. For toddlers, look for adjustable features like drawstring waistbands or stretch panels that accommodate growth.
If your child sits between sizes, choose the larger size for longer use and comfort. For very active toddlers, a snugger rashguard reduces the chance of chafing. If you’re planning frequent pool time, favor suits with reinforced seams and extra stretch so the suit keeps its shape after repeated wear.
Swimwear life depends heavily on fabric and care. Nylon-spandex blends offer the best stretch and fast drying, while polyester blends can be more chlorine-resistant and fade less. After a beach or pool session, rinse swimsuits in cool, fresh water to remove salt, sand, and chlorine. Hand washing in mild detergent and laying flat to dry keeps elasticity intact and prevents shrinking. Avoid heat—hot dryers and direct sun for long periods can break down spandex fibers faster.
If your child swims regularly, look for suits advertised as chlorine-resistant or “long-lasting” swim fabric. These often include higher percentages of polyester or specially treated fibers designed to hold color and shape despite repeated exposure to pool chemicals.
Swimwear is one part of a sun-smart strategy. Pair UPF garments with wide-brim hats or sun hats, polarized sunglasses sized for kids, and reef-safe sunscreen on exposed areas like the face, hands and legs. For infants under 6 months, try to stay out of direct sun when possible and use shaded play areas or beach umbrellas. Sun-safe swimwear plus a few well-chosen accessories keeps the whole family comfortable and protected.
Coverups are perfect for after-swim transitions — think lightweight dresses for girls or long tees for boys that slip on quickly. Rashguards are especially useful because they let kids swim freely while keeping arms and shoulders protected, and you can layer them under a coverup for extra warmth or sun protection.
Safety should always be top of mind. Always supervise children near water, use Coast Guard–approved flotation devices when necessary, and teach basic water skills early. Avoid loose accessories while they’re in the water; strings and ties can catch on pool edges. And remember, even with UPF clothing and sunscreen, direct sun during peak midday hours is best avoided—early mornings or late afternoons are perfect for family-friendly beach time.
Mix-and-match is a game-changer for versatility — pair a neutral rashguard with colorful bottoms or vice versa to stretch wardrobe options. Think of swimwear as a capsule wardrobe for water play: a couple of one-pieces, a rashguard set, and swim trunks can cover most needs. Add small details like ruffles, playful prints, or themed suits (dinosaurs, mermaids, nautical stripes) to spark joy for the kids while keeping practicality in the forefront.
For a family that swims often, two to three suits per child is a solid rule: one in use, one drying, and one spare for emergencies. If budget is tight, prioritize a high-quality rashguard or UPF one-piece and supplement with budget-friendly bottom pieces. Watch sales cycles—end of summer and holiday sales are great times to stock up at a discount without sacrificing quality.
To summarize practical shopping paths: Walmart offers breadth and affordability, making it ideal for fast replacements and value finds. Cerqular is excellent when you want curated, boutique-style pieces with thoughtful prints and tailored fits. Old Navy and Target balance trend and value, Carter’s focuses on infant-friendly sizing and reliability, Gap Kids leans into quality classics, and Amazon provides enormous variety and convenience for last-minute needs. Pick the retailer that aligns with your priorities—budget, style, or specialized features—and you’ll have a better chance of finding the perfect suit.
Timing can save money. Shop end-of-summer clearance sales for deep discounts on last-season styles, or catch early-season drops in spring when stores roll out the newest prints and fabrics. Sign up for retailer newsletters or loyalty programs for early access to promotions and coupon codes. For busy families, a well-timed promo can mean getting a high-quality UPF suit without the usual price tag.
Conclusion: Choosing the right swimwear for your little one blends practicality with personality. Whether you shop Walmart for everyday value, Cerqular for curated pieces, or other trusted US retailers for a mix of price and quality, focus on fit, UPF protection, and durable fabrics. With the right choices and a little planning, you’ll keep kids safe, comfortable and splashing in style all season long.
