Guide buying swimsuits for kids

22 May 2023

Preparing your child for summer adventures requires the right swimwear. Kids’ swimsuits come in a variety of colors and prints, and are available in sizes to fit all body types. When shopping for kids’ swimwear, consider these important factors.

The Right Fit

Choosing the correct size for your child’s swimsuit is crucial. Instead of relying on their age, go with the height of your child. Make the right choices based on their measurements to get the swimwear of the right size. For girls’ swimsuits, measure under the arms around the bust, waistline, and hips.

Height measurement is also necessary to determine if your child needs a tall size. For boys’ swim trunks, measure around the waist. If your child falls between sizes or their size feels a bit too tight, select the next larger size.

When purchasing boys’ swim trunks or girls’ swim shorts, a full elastic waistband provides good comfort. A drawcord or drawstring offers a better fit, but most swim bottoms for boys and girls include these features, luckily.

Chlorine-Resistant Fabric

Look for swimwear made of chlorine-resistant fabric. A nylon/spandex blend is ideal for girls’ one-piece swimsuits or tankinis. The material maintains its structural integrity, ensuring a snug fit without tightness.

A swimsuit made of nylon/spandex with a polyester lining offers comfort and allows for freedom of movement during water activities.

Nylon and spandex are also excellent fabrics for boys’ swim trunks. Boys’ trunks may feature polyester or 100% polyester, a material that resists chlorine, saltwater, and UV rays, dries quickly, and is machine washable or can be hand washed and line dried.

Sun Protection

Swimwear for boys and girls often includes UPF 50 sun protection to shield covered areas from the sun's rays. While sunscreen is still necessary, this feature is helpful.

You can find a broad range of swimwear with sun protection, including one-piece swimsuits, girls’ tankinis, swim separates, and trunks. Additionally, consider polo shirts with sun protection for your child when shopping for summer clothes.

Colors and Prints

Kids’ swimwear comes in various colors and prints, including solid-color swimsuits and trunks in neutral and bright hues. Classic navy and black or tropical orange and bright red are options for summer looks.

Blue is another popular color for kids’ swimwear, ranging from turquoise to cobalt.

Printed swimwear may include color-blocked bathing suits or swim trunks or classic striped styles. Swim shorts, girls’ and boys’ rash guard tees with ocean creatures like fish and sharks are additional options.

Allow your child to choose their preferred color or print so that they'll enjoy wearing their swimsuit.


A beach cover-up is an essential item to remember when buying kids’ swimwear. Boys’ and girls’ cover-ups are available in various styles, and you should choose the one that's comfortable for your child and provides the necessary coverage.

Long-sleeve swim hoodies with UPF 50 are ideal for more coverage and protection at the same time. They're made from polyester and spandex, ensuring comfort, durability, and moisture-wicking properties. Short-sleeve rash guard tees are another option and come in many colors and prints.

Cover-up dresses are also available on the internet in a range of sizes, including petite, plus, regular, and tall. Options include modest cover-ups with high necks and button-front kaftan styles for coverage and comfort.

Accessories for the Beach and Pool

Pick up summertime accessories when shopping for kids’ swimwear. Water shoes protect your child's feet and dry quickly, making them ideal for beach and pool locker rooms.

Beach towels made of soft, absorbent cotton are breathable, fast-drying, and comfortable to lounge on.
