These are guide figures, not medical advice. Absorbency is measured under lab conditions and real-world results vary with fit and activity. If your flow soaks through in under two hours, speak to a healthcare professional.

How to measure your size

Waist

Wrap the tape around the narrowest part of your natural waistline.

Hip

Measure around the fullest part of your hips with feet together.

Fit tip

Between two sizes? Size up for a relaxed, overnight-ready fit.

Measurements are body measurements, not garment measurements. Tolerance is 1–2 cm on finished garments. For private-label orders we can build to your own size spec.
