When it comes to buying your kids bathing suits, the fit is everything, according to Jennifer May, certified lifeguard, Red Cross water safety instructor, and the founder/owner of LifeCycle Swim School, and practical design comes in a close second. “​​Bathing suits should be comfortable—not too tight and not too loose," she tells Verywell Family, adding, “Fun, playful, on-trend prints and designs can help kids get excited for swim lessons.”  While we considered styles and trends when choosing the best places to buy bathing suits for kids, we also considered quality, affordability, and size range availability for all kids from infancy to tweens. Since bathing suits aren’t just for the summer months, we also considered the retailer’s year-round availability of cute suit options, return policies, and shipping. Here are the best places to buy bathing suits for your kids. The easy-to-navigate site always features user reviews and a size chart, which is helpful when determining the right fit. Kid sizes are between XS (4/5) to XXL (14/16) and teens can choose between sizes 8, 10, 12, 14/16, and 18/20. Environmentally conscious families should take note: Nearly all of the Gap swimsuits are made from 100 percent recycled polyester that provides UPF 50+ protection. Your kids will look stylish and stay protected in these choices. We couldn’t resist this brightly colored tankini made of 82 percent recycled materials and 18 percent spandex. We also love that the brand runs frequent promotions on the site to help to sweeten the deal. They also offer free returns and exchanges in-store or online, allowing you up to 60 days to return your purchase if it doesn’t perform well. However, take note that for swimsuits, the original tags and hygienic lining must still be intact, and online items marked mail only can only be returned through the mail. Like most caregivers buying clothes online, we really appreciate the helpful sizing guide. When you click on the size, detailed measurements come up, so it’s easy to see where your kiddo fits. We’ve found sizing tends to run small, so use that chart prior to ordering. With quality that is designed to be handed down from one kiddo to another, Hanna Andersson is committed to utilizing the best of the best materials like organic cotton without compromising on sustainability. If you’re not familiar with Hanna Andersson sizing, use the helpful chart on the site or the online chat feature will clear up any questions. Check the site often for frequent discounts or sign up for emails for a discount code. Highly rated, this rash guard comes in a wide range of unisex colors and sizes. In addition to kids’ sizes, SwimZip features sun protective suits, clothing, and accessories for adults and has family matching options all year long.  Made with a super soft boxer brief liner, these swim trunks are designed with comfort in mind. While on the expensive side, the quality craftsmanship includes a zip-back pocket, quick-drying fabric, an elastic waistband, and drawstrings, so kids can get a secure fit. For a matching duo, all the styles match with adult men’s sizing. Pottery Barn requires a $99 minimum purchase for free shipping but does offer a discounted “ship to store” option. While the returns are not free, you can avoid the pesky charge by returning items directly to nearby locations. Pottery Barn is well known for their personalization options but you should keep in mind that this will cause a delay in shipping time and the item can’t be returned or canceled. With three size options to choose from, you can find a cute cover-up for your kiddo from 2 to 10 years old. Since Pottery Barn Kids doesn’t feature user reviews, check the size chart prior to buying.

What to Look for in Swim Brands for Kids

Design

One of the deciding factors when it comes to picking out swimwear for kids is the design, pattern, and color. Including your kiddo into the selection process can help them get excited about rocking their new bathing suits. While opting for bright, neon colors can help your tot standout while they swim, Certified Lifeguard Jennifer May says caregivers should still prioritize safe swim practices.  “Bright or neon-colored swimsuits may make it easier to spot a child in a pool or aquatic environment," May says. “Variables such as sun or lighting reflection, shadows, water refraction, obstructed views, murky water, and even distracted lifeguards can counteract any advantage of a bright-colored swimsuit. A bright swimsuit cannot be depended on to save a child.”

Sizing

Some swimsuit sizing can be confusing. Most children’s sizing is age-based, but your child may be on the larger or smaller end of that age range. Always check a size chart that includes measurements and take the time to measure your kid. The last thing anyone wants is a swimsuit that is too tight or too loose.

Sun Coverage

Sun protection is so important, especially for kids who are playing outside and possibly hopping in and out of the water over and over again. Look for fabric with a UPF rating of 50 or more to protect your little ones against the sun’s harmful UV rays. In addition to applying lots of sunscreen, the added sun coverage will ensure that they enjoy safe play on sunny days.

Why Trust Verywell Family

Maya Polton is a former marketing manager and current freelance writer who covers food, home, and parenting. She’s also the mom of an 11-year-old son, 8-year-old son, and 4-year old daughter. Maya’s boys are super, super active and can stay in the water for hours. The only thing that’ll get them out is irritated skin, so she’s moved away from mesh-lined bathing suits for them and has seen such a difference. Her fair-skinned girl is a fan of the long sleeve tankinis, which provide great sun protection and easy bathroom access—a win-win in Maya’s book.
