What Makes Great Kids Swimwear?

Before we look at the fun styles, let’s talk about what makes kids' swimwear really great.

Comfort

Swimwear should feel good. It should not be too tight or too loose. Kids need to move, swim, run, and play freely.

Quick-Dry Fabric

Wet swimsuits are no fun! Good children’s swimwear dries fast, so your kids won’t stay wet and cold for long.

Sun Protection

Some kids' swimwear has special fabric that helps block the sun’s rays. Look for swimwear with UPF 50+ if your child plays outside a lot.

Cute Designs

Let’s be honest, cute designs make swimwear even more fun! Whether it’s sharks, rainbows, or superheroes, kids love swimsuits with personality.



Girls' Swimsuits: Cutest Styles for 2025

Little girls love to feel special and stylish at the pool or beach. Here are the cutest girls' swimsuits we’re loving for 2025:

1. Ruffled One-Piece Swimsuits

Ruffles are a big trend this year! From shoulder ruffles to skirted bottoms, these swimsuits are fun and full of flair. Choose soft pastel colors like pink, mint, and lavender.

2. Mermaid-Inspired Suits

Shiny, shimmery mermaid prints are always a hit. Look for suits with scales, seashells, and even little tails for pretend play by the sea.

3. Two-Piece Tankini Sets

Tankinis give the look of a two-piece with the comfort of a one-piece. They’re great for playtime and easy to take off for bathroom breaks.

4. Long-Sleeve Rash Guards with Swim Bottoms

Long-sleeve girls' swimsuits offer more sun protection. They come in bright, cheerful prints like flowers, flamingos, and hearts.

5. Rainbow & Tie-Dye Styles

Colorful and bold, these suits are perfect for girls who love to shine. Tie-dye patterns are big in 2025 and go great with matching hats or cover-ups.

Boys' Swimsuits: Coolest Styles for 2025

Boys want to feel cool, comfy, and ready for action. Here are the top boys' swimsuits that are making waves in 2025:

1. Shark Print Swim Trunks

Sharks are back! This year, look for swim trunks with giant shark teeth, fins, or underwater scenes. They’re playful and eye-catching.

2. Space-Themed Shorts

Rocket ships, planets, and stars—space is a big theme this year for boys' swimsuits. These trunks are great for little dreamers and explorers.

3. Jungle & Animal Prints

Leopards, monkeys, and parrots make swim trunks extra fun. These are perfect for boys who love animals and nature.

4. Rash Guard Sets with Matching Shorts

Rash guards protect from the sun and help avoid scrapes when playing on sand or pool edges. Sets with matching shorts are easy and stylish.

5. Classic Stripes & Navy Blue

Simple stripes and blue tones never go out of style. These trunks look great and go with any rash guard or swim shirt.


Tips for Choosing the Right Children’s Swimwear

Now that you know the cutest styles, here are some tips for choosing the perfect children’s swimwear for your kids.

Size & Fit

Make sure the swimsuit fits well. It should stay in place when kids move, jump, and swim. Check size charts if you’re buying online.

Fabric Feel

Touch the fabric if you can. Soft and smooth fabrics feel better on the skin. Avoid anything that feels scratchy or rough.

Easy to Wash

Kids play hard. Their swimwear will get sandy, dirty, or salty. Choose suits that are easy to rinse and wash, so they’re ready for the next splash!

Add Matching Accessories

Want to complete the look? Add fun extras like matching sun hats, cover-ups, or flip-flops. It keeps your child safe and stylish all day long.

Matching Styles for Siblings

Do you have more than one child? Try matching or themed swimwear sets for boys and girls! Many brands offer kids' swimwear collections that come in both girls' swimsuits and boys' swimsuits with the same colors or prints.

Some cute sibling ideas:

  • Pineapple prints for both

  • Underwater animals like whales and fish

  • Red, white, and blue stripes for the 4th of July

  • Safari animals with matching hats

Matching swimsuits make family photos even cuter, and your kids will love twinning together!

Swimwear That Lasts All Summer Long

It’s important to pick swimwear that doesn’t fall apart after one wash or swim. Good-quality children’s swimwear lasts for the whole summer, and sometimes longer!

Here’s how you can help make it last:

  • Rinse the swimsuit in cold water after every swim

  • Don’t leave it in the sun for too long

  • Hang it up to dry (don’t put it in the dryer)

  • Don’t wring it or stretch it out too much

With care and the right choice, your kids' swimwear will stay looking cute and feeling comfy for every sunny adventure.
