Splish, splash, what’s more fun for your kiddo than a day at the pool in the best toddler swimsuits of the year? Not much, Mama. Basically, anything that allows your little one to wear one of the best toddler swimsuits to the beach, pool, or old-school lawn sprinkler is a day well spent. Our favorite toddler swimsuits of 2021 were vetted for quality, style (aka cute factor), and some were even assessed for sun protection.

“When it comes to swimwear for your tots, coverage from the sun is a real concern,” spills Layne Cross, styling supervisor at Stitch Fix, which offers a selection of toddler swimsuits in their expert-curated fashion subscription boxes. “This season you’ll find that a lot of matching rash guard and bottom sets are on-trend for both boys and girls. They’re a really great option for parents because they provide a bit of extra coverage from the sun, making this trend a practical one.”

Layne suggests bright colors, mini versions of popular adult swimwear trends, vibrant prints, and board shorts for toddlers deserving of front row NYFW seats. She also recommends doing your homework on the earmarks of quality, because it’s hard for flimsy suits to stand up to repeated wear, tear, chlorine, stains, and poop-related mishaps (yeah, those happen).

“Fully-lined swimsuits for girls are usually better quality. The lining acts as a reinforcement to prevent the suit from losing shape or stretching out. For boys, look for a comfortable waistband with a stretch along with a more substantial hand feel, which will sustain the wear and tear of the beach, lake, or pool all summer long.” Check out our top picks for the best swimsuits for toddlers so your tot can be the queen or king of #Summer2021.
