JOLYN suits generally fit more snugly than many other swimwear brands. The best way to find your size is to take your measurements and compare them with our size chart.

If you are between sizes, we generally recommend choosing the larger size.
View our Size Chart here.

Coverage varies by style. We recommend checking the product description and fit notes on each product page to find the level of coverage that suits you best.

You can also view our Bum Coverage Guide for more help.

JOLYN training swimwear is designed for regular pool use and offers strong chlorine resistance compared with standard fashion swimwear.

For more details, please visit our fabric information page.

We recommend rinsing your suit in cold water after each use and letting it air dry naturally.

Please avoid washing machines, dryers, bleach, harsh detergents, and high heat, as these may damage the fabric and reduce the life of the garment.

Some core styles or colours may be restocked, but restocks are not guaranteed. Many prints, seasonal colours, and limited styles may not return once sold out.
