Best Tween Girls Swimsuits

Best Swimsuits for Tweens Guide

Shopping for swim suits with Tweens is less than easy.

Stuck in that space between being a kid and a teenager, Tweens are wanting to be independent yet are becoming aware of their bodies. Our goal is to help our girls pick out swim wear that they feel great in and can handle their jumping, sliding and splashing.

Colors that stand out. Lovely patterns. And pool-party appropriate accessories. All of the adorable tween swimwear has us super excited for summer fun! We understand that tween girls can be difficult to shop for because they’ve outgrown little girl sizes and aren’t quite ready for teen fashion. We’ve compiled a list of the best swimsuit brands for tween girls this year to make your life easier. Plus, there are some really cool cover-ups and poolside accessories. Shop our favorites by clicking on the collage above and scrolling down to see a roster of our favorite tween swimsuit brands. This post contains a list of our favorite stylish tween girl clothing brands!

One Piece Swimsuits for Tweens

For the most active Tweens in the water, a one piece might be the best choice. Stylish suits can still reflect their personalities.

These one piece swimsuits are  fun with a ruffle shoulder and contrast trim.  Or a classic Lands End one piece will work for a day or swim team practice and on to surf some waves.

Tween Swimsuits Two Piece

For Tweens, we like a bikini top with coverage. High neck bikinis are super trendy right now and that is definitely a style we can get on board with. Ruffle tops also let girls feel comfortable.

Look for suits with thicker fabric or a ruffle or pattern around the chest area when shopping for girls in the 9-12 age range who are in the early stages of puberty, particularly if they are self-conscious about their developing bodies.

Tankinis for Tweens

My oldest daughter loves a tankini. She thinks they are comfortable and loves to add a rash guard for beach days to avoid sun burns. These modest swimsuits for tweens stands out due to its playful tropical style print and cut-out styling. It also has a stretchy fabric that is both comfortable and simple to clean.

This tankini from Old Navy has two trends going on – peplum and mixed prints. It’s fun and age appropriate.

This Boden tankini is sold in separates and has coordinating bikini tops and cover ups available so the mixing and matching possibilities are endless!



A tie halter and peplum bottom gives this floral tankini a little extra style.


We hope that you find something in this collection that will provide your young girl with the sun protection and modesty she appreciates while still allowing her to enjoy some summer fun at the beach or the pool.
