How to Measure

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.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
Customers say these high-rise underwear are extremely comfortable and feel like wearing nothing at all. Many appreciate the smooth, silky fabric that provides confidence for light bladder leaks without the bulk of traditional liners. Users find them breathable, lightweight, and effective at staying in place without rolling down. The high waistband offers tummy support and works well under fitted clothing. However, sizing appears inconsistent, with many noting they run small and recommending ordering a size up. Some mention the waistband sits very high, which isn't preferred by all users. A few report issues with the absorbent area placement or coverage. Overall, customers praise their comfort and effectiveness for everyday wear.
