Girls' One-Piece Swimsuits

One-Piece Swimsuits That Keep Up with Her Every Move

At Lands’ End, we believe a girls' one-piece swimsuit should be as bold, bright, and ready for adventure as the girl wearing it. Whether she’s perfecting her backstroke form, ruling the sandcastle scene, or just soaking up the sun in style, her swimsuit should keep up without pinching, sagging, or stretching out by midseason. That’s why our one-piece swimsuits are designed for comfort that moves, colors that last, and confidence that never washes out. Because when she finds the perfect suit, she’s not just swimming—she’s making waves.  

Flimsy Swimsuits Fade—Ours Go the Distance

Not all swimsuits last—anyone who’s dealt with a stretched-out, faded mess after a few wears knows that. Those thin, off-the-rack suits might seem like a deal, but they rarely survive a full summer of sun, salt, and chlorine. 

At Lands’ End, we take a different approach. Our girls' one-piece swimsuits are made with resilient, fade-resistant fabrics that hold their shape and color, swim after swim. We reinforce the seams, fully line our suits for coverage, and add UPF 50 protection because a swimsuit should do more than just look cute—it should perform. Because no one wants a suit that quits before summer even gets started. 


More Styles, More Fun, More Ways to Make Waves

A one-piece girls' swimsuit is just the beginning. At Lands’ End, we offer a variety of girls' swimsuits and swimwear to match her style and summer plans. Whether she wants a sporty fit for swim practice or a kid-friendly rashguard for sun and surf protection, we’ve got options that go beyond the basics.

Classic One-Piece Swimsuits That Stay Put

A girls' one-piece swimsuit should be the last thing worrying her when she’s diving, running, or riding the waves. Ours are designed to stay in place, with soft yet strong straps, full lining for comfort, and chlorine-resistant fabrics that keep colors bold all season long.

Sporty & Playful Swim Styles

For girls who love to mix and match, our girls’ tankinis and swim tops offer a little extra versatility without sacrificing coverage or security. These styles give her the freedom to move while still providing the same durable, sun-smart materials as our one-pieces. Pair it with a personalized beach towel, and she’s ready for a super swim day. 

The Right Bottoms to Complete the Look

Pairing her favorite top with the perfect girls' swimsuit bottoms is easy with our selection of comfortable, stay-put fits. From classic swim briefs to more coverage-friendly options, every pair is made to handle cannonballs, cartwheels, and everything in between. For stellar foot protection at the beach or by the pool, slip on kids water shoes on and enjoy the day.  


Frequently Asked Questions: Kids' One-Piece Swimsuits

If you'd like to learn more about our selection of kids' one-piece swimsuits, check out the answers to our most frequently asked questions down below. 

What should I look for when buying one-piece swimsuits for tweens?

Tween swimsuits need to balance style, comfort, and functionality. Look for a secure fit that moves with her, chlorine-resistant fabrics, and UPF 50 protection to keep up with her active summer days. Bonus points for fun prints or classic solids that match her personality. 

How do I find the right size for a girls' one-piece bathing suit?

Fit is everything when it comes to a swimsuit. Lands’ End provides a detailed size chart with measurements for chest, waist, and hip to help you find the perfect fit. If she’s between sizes, consider sizing up for a little extra growing room. 

How should I care for a girls' one-piece swimsuit to make it last?

To extend its life, rinse it in fresh water after each swim, avoid wringing it out, and let it air dry flat. Skip the washing machine and dryer—heat and harsh detergents can break down the fabric over time.
