What to Look for When Buying Swimsuits for Kids


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.

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 an 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 proper sun coverage will ensure that they enjoy safe playing on sunny days.
