As temperatures rise and school breaks roll in, it’s time to refresh your little one’s wardrobe with outfits that blend comfort, style, and sunshine-ready charm. Parents everywhere are hunting for the best summer wear for kids—pieces that can keep up with endless play, spontaneous picnics, and dreamy family vacations. So, if you’re looking to beat the heat in style, we’ve rounded up the top 10 must-have summer outfits for kids in 2025 that are both parent-approved and kid-loved.

Let’s dive in!

1. Breathable Cotton T-Shirts

Let’s start with a summer staple: cotton tees. They’re lightweight, sweat-absorbing, and perfect for active little bodies. This year, graphic prints and playful slogans are trending. Choose bold, cheerful designs that speak to your child’s personality.

At One Friday World, you’ll find a colorful selection that’s as durable as it is adorable—great for daily wear and backyard adventures.

2. Printed Shorts with Elastic Waistbands

Pair those tees with some comfy printed shorts. The best part? Elastic waistbands! They’re a game-changer for toddlers and older kids alike—easy to slip on and off, especially during potty training or quick changes at the pool.

Look for lightweight fabrics like cotton twill or linen blends. These keep your kid cool while offering enough stretch for cartwheels, tag, and everything in between.

3. Cotton Dresses with Ruffles or Smocking

For the girls, summer is all about twirling in breezy, cotton dresses. In 2025, ruffles, floral prints, and smocking details are stealing the show. These styles are not only pretty but practical—allowing air circulation and plenty of movement.

One Friday World’s summer wear collection includes beautifully crafted dresses that are perfect for birthday parties, brunch dates, or even just a casual stroll through the park.

4. Co-ord Sets for Instant Style

Why stress about matching tops and bottoms? Co-ord sets are a parent’s secret weapon. These matching sets come pre-styled, which means zero fuss during those “we’re running late!” mornings.

From nautical themes to tropical prints, summer wear for kids has never looked this coordinated and cool. One Friday World offers co-ords designed with a keen eye for seasonal trends—your mini fashionista will thank you!

5. Lightweight Rompers and Jumpsuits

Nothing says effortless like a romper. Rompers are ideal for toddlers and preschoolers who want to move freely and still look polished. For girls, soft floral prints are a hit. For boys, utility-style jumpsuits are making waves in 2025.

Choose sleeveless or cap-sleeved options in soft, breathable fabrics like cotton muslin or bamboo blends. Bonus: they double up as great summer wear for vacation photos!

6. UV-Protective Swimwear

Let’s talk about beach days and pool parties. Your kid’s summer wardrobe isn’t complete without some cool, UV-protective swimwear. These suits aren’t just about fun—they’re functional too, helping to shield delicate skin from harmful rays.

Opt for full-sleeve rash guards or two-piece sets with UPF 50+ protection. Brands like One Friday World offer swimwear that ticks both the safety and style boxes.

7. Linen Shirts and Blouses

For a more polished summer look—think family dinners or festive get-togethers—linen shirts and blouses are the way to go. Linen is naturally breathable and dries quickly, making it ideal for warmer climates.

Boys can rock collared linen shirts with rolled-up sleeves, while girls look adorable in embroidered linen tops. Pair them with chinos or skirts for a smart, summer-ready ensemble.

8. Capri Pants and Culottes

Comfort meets style with capri pants and culottes. These mid-length bottoms offer a fashionable alternative to jeans or full-length trousers. Kids stay cooler while still being covered—a win for both moms and playground antics.

In 2025, pastel shades and playful prints are all the rage. Find your perfect pair in the One Friday World collection—they’re made to move with your child.

9. Skater Skirts and A-Line Skirts

Let your little one spin into summer fun with some twirl-worthy skater skirts. A-line cuts are comfy and cute, with built-in shorts underneath for extra coverage and confidence during active play.

Pair them with tank tops or puff-sleeve blouses to complete a fun, flirty summer look. They’re a great way to dress up without sacrificing comfort.

10. Comfy Cotton Nightwear

Last but not least, don’t forget summer nightwear. Hot nights call for ultra-soft pajamas made from breathable cotton or bamboo fabric. Think sleeveless tops, shorts sets, and lightweight nightgowns.

One Friday World’s nightwear line is designed with kids’ comfort in mind—no scratchy tags or tight waistbands here, just blissful sleep after a day of fun.
