The best swimsuits for tweens are comfortable, provide protection, and are also stylish.

While we start to see a variety of different swimsuits make their appearance in the summer, finding one appropriate for your tween girl can be tricky.

The most challenging thing you will face when shopping for a swimsuit for your tween is that many of the swimsuits available are not very modest. It seems like each year new styles cover less and less.

Something else that makes it challenging is that your tween is getting older and independent. She’s starting to make her own clothing choices and may want something a little more revealing.

Luckily, we’ve gathered some of the best modest swimsuits for teens. They feature protection and coverage from the sun, while remaining stylish.
