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 month ago
Customers say these leakproof underwear are exceptionally comfortable and soft, feeling like regular underwear without bulk. They praise the excellent fit and reliable protection for periods and bladder leaks. Many appreciate the high-rise coverage and smooth, no-show design under clothing. Users frequently mention the durability, with pairs lasting years through regular washing. The stretchy, breathable fabric stays in place throughout the day. While most find them true to size, some recommend sizing down for a snugger fit. A few note concerns about recent design changes making them bulkier, and some mention limited color options for heavy protection styles.

Their leakproof period products are amazing. By far the most comfortable and effective of the ones I’ve tried. I’ve purchased several pairs. I had an issue with a discount code during checkout last time but customer service reached out to me right away.
