How to Wear
Position the waistband of your swim undies comfortably high on hips, creating a gentle curve under the belly button.
This shape keeps them discreet under her swimwear. Don't pull them up too high though, that can be uncomfortable. They only need a little lift to do their job.

Top Care Tips for Girls Period Swim Underwear
Keeping her swim undies fresh and fabulous is super easy! Here’s a quick guide to keep them looking great:
• BEFORE HER FIRST WEAR: Machine wash them in cold water to activate the tech layers and make sure she's fully protected from her first period swim undies wear.
• AFTER SWIMMING: Rinse the swim underwear in lukewarm water until water runs clear. This step really helps maintain their magic and keeps water resistant coating in tip top shape!
• IF RINSING IMMEDIATELY ISN'T POSSIBLE: Store them in a waterproof bag (a ziplock works just fine!) and rinse them when you get the chance. Just make sure they don’t dry out!
• HOW TO WASH: Toss them in the machine on a cold cycle.
• HOW TO DRY: Air dry only—no dryers, please. The tech layers are really not a fan. Ensure they are fully dry before storing them away to avoid any unpleasant damp smell.
How to Measure
TOTAL WAIST CIRCUMFERENCE: Circle a measuring tape around her waist just below the belly button. Make sure the tape is sitting evenly all the way around.
HALF MEASURE: If you don't have a measuring tape, you can lie a pair of her underwear flat and do a half measurement of the front. If they measure around 2cm either side of stated measurement for each size, you've got yourself a winner!

The care instructions for swim period underwear are just like how you look after our regular period undies. Check out the simple 3-steps needed to keep them in tip-top shape here.
Note though, that since swim undies come into contact with chlorine or salt water, it's crucial to rinse them out right after a swim to protect the waterproof coating and keep our swim underwear working like a charm.
