When it comes to prepping for fun in the sun with your little one, the list of essentials ranges from the functional (sun screen, sun hats, swim diapers, and more) to the fashionable (two words: baby sunglasses). But one item that crosses both categories? Infant swimsuits. Not only is baby swimwear adorable, it is also designed to help protect sensitive infant skin from the elements. And while your itty-bitty might not be hitting the pool just yet, baby swimwear is still useful during those younger months too (think beach visits, water play, and the like).

Whether you’re planning a beach vacation or just stocking up on warm weather essentials, there’s no shortage of baby swimsuits to choose from. Here, we’ve broken down everything you need to know about these bitty bikinis and briefs—from the different types to our favorite brands and top picks.

Types of Infant Swimsuits

Infant swimsuits aren’t one size fits all. Here is a look at all of the different types of swimwear for your little ones.

  • Baby rash guards: Not just for surfing, baby rash guards are a top that can be worn with briefs or over one and two-piece swimsuits. Typically long sleeve, baby rash guards help offer extra protection from the sun, sand and water temperatures.
  • Full-coverage baby swimsuits: Since the American Academy of Pediatrics (AAP) recommends not using sunscreen on babies younger than 6 months, parents need other methods for protecting infant skin from the sun. Enter full-coverage baby swimsuits, which are one-pieces with both long sleeves and long pants that leave only the hands, feet and head exposed.
  • One-piece baby swimsuits: One-piece swimsuits can be long-sleeve, short-sleeve or sleeveless—but typically leave the legs fully exposed.
  • Two-piece baby swimsuits: Bikinis, tankinis and rash guard/swim trunk combos all fall into the two piece category.
  • Baby swim trunks: Baby swim trunks are shorts-style swimwear. They come in both board short (looser fit) and brief (tighter and shorter) styles.

How to Pick the Best Infant Swimsuit for Your Baby

Not sure which type of baby swimsuit will work best for your little one? Here are some things to consider.

  • Fit and sizing: Baby swimwear is supposed to be snug: You want it to be tight enough to avoid uncomfortable bunching and exposing skin to the sun’s rays, but not so tight that it irritates your little one’s skin. Also, swimwear sizing can be different from other infant clothes, so it’s important to try on to ensure a proper fit.
  • Fabric: The swimsuit’s fabric can help offer additional protection from the sun’s ultraviolet rays. Fabrics like polyester and nylon offer more sun protection than natural fibers, and darker fabrics tend to offer more UV protection than lighter ones. Fabric with a UPF50+ rating protects against 98 percent of the sun’s ultraviolet rays.
  • Features: Some useful features to keep an eye out for: Zippers make swimwear much easier to put on and take off (especially when wet), hoods offer extra sun protection, and some baby swimsuits even come with built-in swim diapers.

Best Infant Swimsuit Brands to Shop

As with all things baby gear, there are certain brands that do it better than the rest. For quality infant swimsuits that are cute to boot, check out these top places to shop.

  • Tea Collection: Consider Tea Collection your one-stop swimwear shop. The brand has every type of baby swimwear (including coordinating sun hats), and Tea Collection offers big kid and adult sizing for a matching family swim moment. All of the brand’s swimwear offers UPF 40 protection from the sun, and come in a ton of colorful prints and designs. Bonus: The brand donates 10 percent of all of its profits to organizations that benefit children worldwide.
  • Janie and Jack: This timeless brand offers high quality baby swimwear—including one-pieces, two-pieces, rash guards, swim shorts and accessories—in classic designs, making them perfect for passing down from child to child. Extended sizing (up to size 18 in some designs) allows for matching moments with older siblings, and their new Recycled Swim line offers suits made from sustainable fabrics (including one made from recycled plastic bottles). We also appreciate the UPF50+ sun protection found in most of their designs.
  • Boden: Vibrant colors and cheerful prints make Boden’s baby swimwear one of our favorites, but the brand focuses on function as well as fashion. All of their baby swim trunks come as a set with a long-sleeve rash guard; their full-coverage swimsuits feature a zipper for easy on-and-off and their baby cover-ups double as a towel to help dry off. Boden also offers adult and child sizing, making it a great place to shop for family swimsuits.
  • Hanna Andersson: Long-lasting, sun-blocking, fast-drying swimwear for the whole family? Sold. Hanna Andersson offers everything from tiny two-pieces to full-coverage one-pieces and everything in between—all with fun designs. Little ones will also love the brand’s character swimwear, featuring favorites like Disney princesses, Mickey Mouse, and Star Wars.
  • Spearmint Love: If neutrals, boho prints and fashion-forward designs are more your vibe, look no further than Spearmint Love. With dozens of stylish offerings from brands like Rylee & Cru, Shade Critters, Gerber Childrenswear and more, Spearmint Love makes it easy to find an adorable suit for your little one—without sacrificing on important factors like sun protection and comfort.
  • Nordstrom: Not only is Nordstrom a great retailer for all things baby swim-related (thanks to top-quality brands such as RuffleButts, Little Me, Shade Critters, Green Sprouts and more), it’s also ideal for the time-strapped parent who is looking for one place to shop for all the things. Whether it’s swimwear for Mom and Dad, fresh beach towels or vacation footwear, the department store takes care of the whole family with one stop.
  • Old Navy: When it comes to baby swimwear that’s both affordable and adorable, Old Navy reigns supreme. The retailer offers tons of stylish options at budget-friendly prices (some as low as $7!), and many of their infant swimsuits come with parent-approved features such as snaps at the crotch for easy diaper changes and UPF protection fabric.

Even among these seven top brands, there are still hundreds of baby swimsuits to choose from. We’ve narrowed it down even further, selecting our favorites across every category, from bikinis to full bodysuits.
