Suit Up the Whole Family at Old Navy’s Summer Swim Sale: One-Pieces, Rashguards, & More Start at $7 (2024)

If my three kids had their way, we’d spend all summer lounging in the pool, stomping at the splash pad, or running around the water park. At the start of the season, I like to update their swimsuits so they have options that are comfortable, well-fitting, and safe for water play (I recently learned that blue-colored swimwear is unsafe). Kids’ swimsuits can be shockingly expensive, so I turned to one of my favorite places to shop for high-quality, affordable clothes: Old Navy. (I live in its linen blends during summer!)

Right now, Old Navy is running a massive sale on swimwear for the whole family, with up to 50% off rashguards for babies and toddlers, one-pieces and trunks for kids, and even matching suits for adults starting at just $7. In addition to the fun patterns, I appreciate that all Old Navy swimwear is made from quick-drying, sun-resistant UPF fabric that keeps its shape throughout the season—and that each of these 14 picks is under $25.

Ruffle-Trim Bikini and Rashguard Swim Set

Wrestling a wet one-piece off a squirmy child for a swim diaper change or potty time can be a nightmare, but many two-piece swimsuits don’t offer much coverage. If you’re looking for a great balance of sun protection and easy pull-down bottoms, this set with a long-sleeve rashguard and a ruffled bikini bottom is a winner. Multiple reviewers rave about its high quality, while another asserted that the suit is “even cuter in person.” It’s available in four prints and sizes 12-18 months to 5T.

Printed Long-Sleeve Swim Rashguard Bodysuit

The American Academy of Pediatrics recommends against using sunscreen on babies younger than 6 months old unless absolutely necessary. That means babies largely rely on fabric to protect their skin. With a banded neck, long sleeves, shorts, and built-in UPF 50+ sun protection, this rashguard bodysuit offers impressive defense against harmful UV rays.

Caregivers will also love that it has a full zipper and hidden snaps along the crotch inseam to make life easier. Reviewers noted that “the material is stretchy and the zipper is long enough that allows easy dressing and undressing while wet.”

Graphic Rashguard Swim Top & Trunks

This two-piece set for toddlers includes a swim shirt and trunks, both with built-in sun protection. “Love the material—very flexible for an active toddler,” one buyer noted, while I also appreciate that the trunks have an elasticized waistband and drawstring to accommodate growing kids. At 50% off, the set offers great value, but if you’d prefer a fuller range of prints, the toddler trunks also come in additional colors.

Printed Swim Trunks

These sweet trunks are just the thing for a baby’s first water play experience. They’re available in sizes 0-3M through 18-24M in multiple fun designs, including several prints that can match the family like this flamingo pattern. Pair the trunks with a long-sleeved rashguard swim top for full sun protection on your next pool day.

Side Cutout One-Piece Swimsuit

This nifty cutout one-piece swimsuit has an asymmetric neckline with one tank sleeve and one spaghetti strap. The fully lined suit is “super cute and very comfortable for my daughter and fit her perfectly,” commented one reviewer. It comes in a tropical print, sunshine print, and textured kelly green.

3-Piece Rashguard Cami Swim Set

Swim sets like this one are a great way to save even more money. The three-piece matching set comes with a long-sleeved rashguard swim top, a camisole tankini swim top, and coordinating swim bottoms. The cami top has a straight neck, spaghetti straps, and a ruffled hem, while the bikini bottoms have ruffles along the leg openings. “Adorable, practical, and very reasonably priced,” said one reviewer—what more could you want?

Swim Trunks

Nearly 500 five-star ratings can’t be wrong: These swim trunks are awesome. Available in 15 prints and four solid colors in kids’ sizes XS to XXL, the bottoms have built-in mesh lining, an elastic waistband, an adjustable drawstring, and a back pocket. If you need more than one pair, you can also buy a two-pack in two color combinations.

Printed Cutout One-Piece Swimsuit

Looking for a compromise between a one-piece and a two-piece swimsuit? Try this sweet suit that’s technically a one-piece, since the top and bottom are attached on the sides, but is fully open through the midsection in the front and back. The suit has a scoop neckline and wide shoulder straps and comes in fun summer prints in kids’ sizes XS to XXL.

Plus, this “super cute” swimsuit is made from “durable fabric” and provides “plenty of coverage,” as one shopper shared.

Printed Tie-Front Bikini Swim Set

Got a tween begging for their first two-piece? This cute set offers more coverage than other bikini options if you’re on the fence. Its swim top features a scoop neck, wide shoulder straps, and a tie-front embellishment at the base, while the matching swim bottoms offer full coverage in the back and aren’t too low on the waist. One reviewer gushed that it’s “easily my daughter's favorite swimsuit! Lots of coverage and the design is adorable!”

Short Raglan-Sleeve Rashguard Swim Top

This swim top is made of quick-drying, stretchy fabric that offers maximum sun protection. Reviewers praised the shirt’s durability, quality, thickness, and softness, noting it’s true to size and a good length. “I love that it is a neutral enough color to work with several swim short combos,” one shopper noted, adding: “Plus, no sunburn!”

Printed Back-Cutout One-Piece Swimsuit

This fun one-piece swimsuit for kids boasts a high, straight neckline and a small scoop cutout at the lower back. Old Navy customers have loved that it’s fully lined, true-to-size, and available in bright, colorful prints. The handy adjustable spaghetti straps were also mentioned in many reviews as a favorite feature for growing kiddos. Available in kids’ sizes XS to XXL, the range should cover children sized 5 through 20.

Printed Swim Trunks

Parents and caregivers can get in on the swimsuit savings, too. These printed swim trunks even match the toddler and kid versions in several patterns so the whole family can match. Available in regular and tall sizes up to XXXXL, the loose-fitting shorts have built-in UPF sun protection and a 7-inch inseam, though you can buy a pair with a 5-inch inseam for the same sale price.

One-Piece Swimsuit

This simple one-piece is currently on sale in over a dozen colors, including this lovely red floral design that’s just $11. The suit has adjustable spaghetti straps, a scoop neckline, removable pads, and elasticized leg openings, and it’s “super soft and comfortable” to boot, as one reviewer noted. It comes in sizes XS through 4X, though some sizes are already starting to sell out.

Side-Tie Swim Dress

For caregivers who prefer a bit more coverage, this swim dress has a square neckline and thick tank straps that are wide enough to cover bra straps if desired. Over 600 shoppers have given it a five-star rating, with one reviewer exclaiming, “It fit perfectly and was a real confidence booster!” On sale for as low as $23 in sizes XS through 4X, the side-tie dress also has removable pads and built-in briefs.
