Taking measurements

If you are between sizes, we advise that you use the hip measurement as the more important one to choose the best fit. You may also want to opt for the larger size – menstrual undies have more layers in them than regular, everyday underwear – which makes their sizing run slightly smaller (the more absorbent the model, the more layers it has).

Waist – measure just above the belly button, below your ribcage. Refrain from sucking your tummy in – after all, it’s about finding a fit that feel comfortable 🙂

Hips – hold the measuring tape around the widest part of your hips

Additional tips:

Hold the measuring tape flat against your waist/hips, snug but not too tight (give it a little room, so that it doesn’t dig into the skin).

When choosing the fit of menstrual undies, it’s a good idea to measure yourself specifically at the time of your period. Many of us have a tendency to retain water at the start of the cycle, which may cause measurements to vary slightly over the course of the month.
