Toddler Swimsuits

A toddler swim suit should rock larger-than-life graphics. We’re talking punchy color blocks and retro flames that remind you of summers at the water park and long lake days that end with fruity popsicles. But behind our bold prints is real construction. Each item is made from a soft, stretchy, quick-dry blend (90% polyester, 10% spandex) that holds up through every run down the Slip ‘n Slide. Whether it’s for the pool, lake, or beach, these are styles they’ll actually want to wear on repeat.

Standout Styles To Know

Our swimsuits are made from quick-dry, lightweight material that makes transitions from water to playground to mealtime way less chaotic. Here are four of our top picks:

• Heater Boardies: This combo is a HEATER! If you’re raising a little heat seeker who loves to stand out, this checkerboard and flame mashup is for you.
• Fast As Duck One Piece: A no-fuss one piece with adjustable everything. If your daughter likes to go fast, this souped-up duck is quicker than quack.
• Daisy Checkers One Piece: We’re obsessed with this sweet-meets-cool vibe that combines flowers and checkers. Perfect for girls who want style and comfort in one go.
• Sticker Slap Boardies: All your kid’s favorite things (smiley faces, motorcycle helmets, checkers, and more) slapped, stacked, and ready for summer. If you know anything about us, you know we can’t get enough of stickers here at Little Trouble. If your little daredevil feels the same, these boardies are the perfect poolside personality statement.

Whether they’re hopping in and out of the pool or creating wet footprints across your deck, these suits dry in a flash and stay super soft. Less soggy fabric means more nonstop fun!

Designed For Wiggly Kids

Getting swimwear on (and keeping it on) shouldn’t feel like a wrestling match for you or your child. All of our toddler swimsuits are designed to be worn in and out of the water all season long, with thoughtful details that make getting dressed way simpler. Just easy-on, easy-off comfort for kids who don’t have time to sit still.

For the girlies, our adorable one pieces feature adjustable shoulder straps and ruched sides for a flexible, comfy fit that stays put but still makes potty breaks a breeze. The true-to-size cut is stretchy enough to move with them all summer.

For the boys, our boardies are just as convenient. Each pair comes with a soft elastic waistband and functional drawstring for the perfect fit. That means no pinching or sagging, even after a big round of snacks. It’s made-to-move gear for every lakeside BBQ, birthday party, and salty summer night.

From Beach To Boardwalk: Styling Swimwear As Streetwear

You know how it goes. Tiny bare feet splashing through waves at 9 AM, then kicking up dust on the boardwalk by noon with no outfit change necessary. At Little Trouble, our toddler swimwear is built for more than water. When you pick pieces with bold graphics, quick-dry comfort, and fits that lean slightly oversized, they’re the centerpiece of any summer fit. Your little one can roll straight from the sand to the street without missing a beat.

Make Swim Shorts Work Overtime

A toddler bathing suit, like the Heater Boardies or Sticker Slap Boardies, doubles as statement shorts once the sprinklers shut off. Pair them with a slouchy tee like the Fast is Fun shirt for a moto-inspired look, or layer on the cozy PUNK Hoodie when the breeze kicks in. This fan-favorite pullover is made from our signature Little Trouble blend (perfect parts organic cotton and bamboo), complete with a cheeky embroidered “MOM” patch on the sleeve. Toss on some Vans or Converse, and your little one’s streetwear game is locked in!

Turn One Pieces Into Whole Fits

Our one pieces don’t just turn your daughter into the cutest kid at the pool (but we agree that is a nice bonus). They’re the ultimate summer layer once the floaties come off. Throw an oversized Never Grow Up tee or a Little Bloomer Pink Corduroy dress on top, and suddenly it’s a beach-to-lunch fit with smiles all over. Perfect for girls who want to keep it moving, from tidepools to taco stops.

Comfort That Doesn’t Clock Out

All Little Trouble swimwear is built from ultra-soft, stretchy, quick-dry fabric, so your kid stays comfy in and out of the water. Whether they’re still damp from a lake jump or drying off with popsicles by the pool, there’s no clinging or outfit complaints. Just easy-wearing pieces that make sense for independent kids who don’t want to stop the fun. With the right swimwear-as-streetwear moves, your kid dresses the part and owns it, all the way from wave-chasing chaos to the golden-hour slow drive home.

Fit Guide: Dialing In That Wave-Ready Fit

Sizing shouldn’t be a shot in the dark, especially when your toddler’s got places to be. A well-fitting swimsuit that doesn’t pinch means fewer meltdowns and more time playing in the sun. Here’s how to get it right:

Little Trouble Sizing: What You Need To Know

Most Little Trouble toddler swim styles run from 6–12M up to 6–7T, with a fit based on average U.S. age range sizing (50th percentile). If your kid typically wears a 3T, our 3T will likely work great. Got a fast grower or a bigger build? Size up to stretch out that wear time. A little extra length means more wear and more value. If the suit still looks good after all that, you can pass it down to the next wild child in line. 

Fit Tips From The Real Ones

Around here, a great fit is about making the most of every messy, sun-soaked minute. The goal is freedom and comfort wrapped in standout style. Our material is soft and silky smooth, even for kids with sensitive skin. Plus, stretchy fabric and adjustable waistbands let your kid focus on being bold, brave, and totally themselves. But don’t just take our word for it! These reviews speak for themselves:

• Maylisa says: “They fit my toddler perfectly around the waist and are just the right length to still show off the chunky thighs! Everything we've gotten from Little Trouble is so well made with soft, comfortable material; even for my little one with severe eczema.”
• Sarah M. says: “Looks great. Fit is true to size, though probably on the smaller end, so size up if you’re in doubt.”
• Dede says: “These are so dang cute! They do run a little small, so my dude only could wear them a couple of weeks. I wish I would have sized up for sure! Size up one mamas!”

Accessorizing The Suit With Hats And Shades

Summer’s all about playing hard and living even harder. Between cannonballs, scooter crashes, and popsicle runs, your toddler’s swimsuit is just the start. Accessories that double as sun protection (and don’t kill the vibe) come down to two key extras. Hats and sunglasses are the go-tos for keeping kids covered without slowing them down.

The Hat Lineup: Shade That Stays Put

Never underestimate the power of a good hat. Think of them as portable shade, shielding little faces and tiny necks from relentless rays. Here are four hats your kid will want to keep on repeat all summer long:

1. $ For Dirt Bikes Snapback: Some kids wear hats that say exactly what they’re saving up for. This black-on-beige dirtbike hat is for the little dreamers who are already planning their garage lineup. With a structured six-panel fit, flat brim (curve it if you want), and durable cotton-twill material, it’s built to last through park hangs and sandy wipeouts.
2. PUNK Snapback: This punk hat brings the attitude. Featuring bold 3D embroidery and a 5-panel structured fit, the PUNK hat levels up any wardrobe. Pair it with the matching hoodie for the ultimate set, or mix and match with your kid’s freshest fits. Either way, this snapback holds its own.
3. Loverboy Trucker Hat: Bold colors, big heart. The lover boy hat is a showstopper with a breathable mesh back and the kind of fit that works all day. The 3D embroidery, custom tape, and clip label details make it feel extra special without overdoing it.
4. Smiley Bucket Hat Checkers: This reversible smiley face bucket hat is totally essential and goes with every outfit imaginable. In this style, you’ll find a black-and-white checkerboard with fuzzy smiley face patches on one side and “Smile Squad” embroidery on the reverse. Whether you go with the classic checkers/black, tan/tan, pink/tan, blue/tan, red/tan, or black/yellow color combo, this bucket hat brings shade and style in one flip.

Each style comes in three sizes: 50cm for babies (0–2 years), 52cm for toddlers (2–5 years), and 56cm for youth (6+). All of our snapbacks are adjustable, while our bucket hats are made to grow with your kid.

Sunglasses: Mini Size, Major Protection

Honestly, nothing says “summer legend” like a pair of mini aviators or chunky, colorful wayfarers with big attitude. We’re talking toddler-sized sunnies with UV-blocking power and impact-resistant frames tough enough to survive every tumble and wipeout. They’re legit defense for delicate eyes from all that unfiltered sunshine.

Suit Up, Then Gear Up

The swimwear might be the star, but the extras are what keep summertime safe. Toss a hat in your beach bag, keep shades within reach, and never let the sunscreen run out. Because when your kid’s out there chasing waves, jumping curbs, and turning every sprinkler into a stunt course, sun safety shouldn’t interrupt the fun. It’s part of the ride. Pack smart and let the good times roll.
