Why it's important you only wear BREATHABLE period underwear.

How Does Knicked Swim Work?

Our Period Swimwear Collection is more than just a fashion statement; it's a revolution in aquatic wear, empowering females especially tweens & teens to embrace their love for the water without any period-related concerns. Dive in with confidence, surf with style, and redefine your swim experience with our versatile range of period swimwear without the fear of leaks. It's time to make waves, make memories, and make a splash with absolute confidence

* All swimwear purchased on sale is excluded from our free exchange offer but can be returned in as new condition within 30 days of purchase for a gift voucher to repurchase another size or style. All swim sets containing non period proof additional items are not created by Knicked so therefore sizing may differ and are matched to our sizing by waist measurements only.
