Size Guide
Fri Period underwear are designed to fit and flatter all body types and sizes.
Our size chart below will help you choose which Fri size is for you. Choosing the perfect fit is also a matter of personal preference. Some prefer a looser first, whereas others prefer the support of a slightly tighter fit.
Fri Period underwear are made with US-grown organic cotton with just the right amount of stretch and give to let you move easily, while also providing a comforting level of support.
Not sure how to measure?
- Your hip measurement is the widest part of your hips.
- Your waist measurement is the part just below the bellow button.
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.
