Your Questions, Answered

How does Period Swim work?

Scarlet Period Swimwear features a multi-layered leak-proof technology that absorbs and contains fluid. An added waterproof inner layer then works to stop any menstrual fluid from leaking out, and water from getting in. Click to read more on the magic of Period Swimwear.

How do I store them post-swim

We recommend travelling with a water-resistant travel bag such as our Toiletry Bag. Give them a good rinse to remove any chlorine or salt water, before stashing away. Once home, either machine wash in cold water with mild detergent or if wearing them again soon, hang them out to fully dry (the sunnier the better). 

Are they easy to wash?

After use, give them a good rinse in cold water to remove any chlorine or salt water. Then, machine wash in cold water with mild detergent (no bleach!). Try our Laundry Bag to safeguard them on laundry day. Then just hang out to dry (the sunnier the better) or tumble dry on low - that’s it! 

TIP: If it’s your first wear, pop them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more

Why buy a Swim Set?

Save money and stay ready with our Brief + Swim BFFs Set! It features these killer High-Waisted Period Swim Briefs for in the water, a pair of Period Bikini Briefs for when you’re out, and a waterproof Toiletry Bag to store your wet togs in until you get home.

Do I need to wear a cup, tampon, or pad too?

Depending on the absorbency level you choose and the heaviness of your flow, you can wear our period panties on their own or as backup protection along with a Period Cup or tampon.

What does the absorbency level mean?

Super Light: Holds up to 1 teaspoon, which is equal to less than one regular tampon. Think of it as a new-age panty liner, so it’s great for spotting, light leaks and discharge. Try: Invisible Thong

Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or one pad. This is for light days to save you from pesky drips, discharge, and lighter flows. Try: G-String or Bikini Brief in Light-Moderate

Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Go for this on moderate days or as extra defence on heavy days with our Period Cup. Try: High-Waisted Brief or Bikini Brief in Moderate-Heavy

Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads. Our heavy hitters are great to wear on their own, day or night. Try: Boyshort or Period Cup

How do I pick the right size for me?

We get it, sizing for bottoms is anything but standardised. Which is why this size guide will help break it down for you. Make sure to check both our numeric and letter sizing so no confusion (ie. our large is a 12).

When in doubt, feedback tells us better to size up. Still confused? You can also email us for help at support@scarletperiod.com.
