Finding your perfect size shouldn’t feel like a maths exam. Our period underwear is designed to stretch, move, and support you. Choosing the right size will give you the best leak protection and all-day comfort. Scroll on for our size charts and some useful sizing tips.
Measure in two easy steps:
Waist
Measure around your natural waist (where your belly button sits).
Hips
Measure around the widest part of your hips and bum.
Helpful tip
Measure on your bare skin or over underwear (not jeans) and don’t pull the tape too tight.

Real people, real sizes
Fri Period underwear is designed to fit and flatter all body types and sizes. Choosing the perfect fit is also a matter of personal preference. If in doubt, we recommend sizing up.
Due to the cut of our low-rise hipsters, we find most people have to size up for this shape. For example, if you're buying the classic briefs in size Medium, we recommend choosing Large for the low-rise hipsters.
If you find your waist and your hip measurements fall in different categories in the chart above, then we would recommend choosing the size that best aligns with your hips first. This is more likely to provide the best fit for you.
We know it can be hard to get sizing 100% right when ordering online. If you're happy with your products but the sizing isn't quite right, email us at hello@friperiod.com.au with your order number and details, and we'll send the right size out to you at our cost.
Please note this is available only to first time customers and for one order.
Not sure where you land? Totally normal — bodies don’t follow charts.
