Baby & Toddler Girl: One Piece Swimsuits & Rash Guards

Dress her up for summer fun with cute little one-pieces made to be seen.

Ruffled One-Pieces for Little Mermaids to Love

Swim diaper? Check. Floaties? Check. Adorable yet comfortable swim attire? Double-check! Keep your sweet one covered in a toddler girl rash guard or a baby girl one piece swimsuit. Baby burns are no fun on soft, delicate skin, so we've designed full-coverage short- and long-sleeve one-pieces that encourage safe poolside play all afternoon. Every one piece bathing suit and baby girl rash guard is made with UPF 50+ fabric that will last through many dips in the pool and frolics through the sprinkler. To be extra safe (and extra cute), add a floppy toddler girl sun hat that ties at the chin and matches her fashion swimwear.

Browse our rash guard toddler girl selections to find long-sleeve swimwear with ruffles and bows around the legs, perfect for beach days. Stripes and florals make for fun prints on toddler girl rash guard swimsuits, so dive into the deep end with colorful selections or bright accessories. Each rash guard and toddler girl one-piece swimsuit features three buttons on the bottom for easy diaper changing because being adorable should also be convenient and kind to the skin. Shop fun florals, tropical leaves, or jungle animals, or dress her up in classic styles like black and white stripes.

If your little girl loves skirts, she'll happily splash in a skirted one-piece or rash guard with bows for an extra dose of cuteness. The options are endless for cute baby girl summer clothes. Combine polka dots and stripes or keep it simple with a bright solid and an eye-catching pattern. Find rear ruffles on every look in a complementary color, and make summer memories to cherish with RuffleButts in tow. Buy your little mermaid the swimwear she'll love this summer! Once the summer fun comes to an end, keep up the stylish looks with adorable back to school clothes.
