Pretty and Practical Two-Piece Baby Swimsuits

If you’re looking for practical, adorable swimwear for your baby, look no further. Comfy, durable, and oh-so-cute, RuffleButts two-piece baby swimsuits check all the boxes.

With separate baby swimsuit pieces, you’ll get baby ready for the beach in no time. Plus, a two-piece baby swimsuit silhouette makes diaper changes easy, even when you’re on the go (or right out of the water). We keep a wide variety of baby swimwear in stock, in almost any fabric type or style. From long sleeve rash guard tops for your baby boy to sweet tankinis with ruffles and bows for your baby girl, your little one is sure to be stylish this summer. Our patterns and prints range from monochrome stripes to colorful mermaid scales, so you can find the perfect bathing suit for your family. 

Pick out a cute and comfy baby swimsuit set for your bundle of joy, and top it off with a matching swim shorts, swim trunks, swim headband, or swim hat. All our swimwear is made from UPF 50+ fabric that offers excellent sun protection, so you can rest easy while your little one splashes away. We’ve even designed coordinated swimwear in adult sizes (and parent-approved silhouettes), so you can proudly display your love for your baby and get all your summer shopping done at once.
