Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 1 week ago
Customers say these cotton leakproof underwear are exceptionally comfortable and soft, feeling like regular underwear while providing reliable protection. Many appreciate the cotton fabric for its breathability and comfort, especially for all-day wear. The absorbent liner effectively handles periods, bladder leaks, and discharge without feeling bulky or wet. Users find them true to size with good coverage and no riding up. However, some mention the floating gusset design can shift or bunch, with the liner not fully attached on the sides. A few note the seams are thicker than other styles and may show through tight clothing. Most praise the confidence and peace of mind these provide, with many becoming repeat purchasers.
