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

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.

While I don't have periods anymore, these are great for occasional boughts of incontinence, especially sneezing! If you know, you know. 😂 They're super comfortable & no show under my leggings.

MSMarilyn S.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Rated 5 out of 5 stars4 days agoFaves
These are my favourite period underwear. The high waist just adds an extra comfort when I’m feeling so crummy and they provide all the coverage needed. I wear the mid level absorbency so they are back up on heavy days and full protection on lesser flow days. I have many pairs of these and I couldn’t function without them!
LTLily T.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Rated 5 out of 5 stars5 days agoAwesome undies
Very comfortable , I got the white with the pretty lilac flowers in L. The nice lady staff member took my measurements so I got the perfect size. Usually a size 14 in pants.

LSLois S.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Rated 5 out of 5 stars1 week agoComfort
Comfort and a product the actual does what is designed for. Sometimes top part rolls but that is also due to weight change. I don’t need mine for periods but small drips of urine but mostly sweating (especially summer and anxiety). No smell which is great, no wet underwear, great!! Lovely texture, soft and really no pantie lines. 😊
