Know Your Flow

The first step in finding the perfect period underwear is understanding your menstrual flow. Are your periods light, moderate, or heavy? This information will help you determine the level of absorbency you need.

Consider Your Body Type

Body shape can play a role in how period underwear fits and feels. Some individuals might prefer a higher-rise waistband for extra coverage and support, while others might opt for a lower rise for a more minimalistic feel.

Material Matters

The material your knickers are made from is crucial for both comfort and functionality. All Scarlet underwear is made from breathable, moisture-wicking fabrics that are gentle on the skin. Our core range uses GOTS-Certified organic cotton, the High-Waisted pants use soft modal cotton (which has more stretch than the organic cotton), while the Thong uses lightweight polyamide. All fabrics are free from chemical treatments, including PFAS (independently lab tested).

Measure Up for the Perfect Fit

Just like with any other clothing item, sizing matters. Ill-fitting period underwear can lead to discomfort and leaks. Here’s how to find your perfect fit:

• Stand up straight, relax your stomach muscles, and locate the narrowest part of your waist. This is typically just above your belly button. Take the measuring tape and wrap it around your waist, making sure it's snug but not tight.
• Locate the fullest part of your hips, usually around the hip bones. Wrap the measuring tape around this area, ensuring it's parallel to the ground and not too tight or too loose.
• Remember that period underwear uses firmer elastic materials to provide a secure fit (no one wants leaks after all!). If you are in between sizes, it’s probably safest to go the bigger to allow for bloating.
• If you're still uncertain about finding the perfect size, don't hesitate to reach out, support@scarletperiod.com. We’d be happy to help.

Now you know your size, why not find out to clean period underwear so that they remain hygienic, safe, and comfortable.
