Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
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.

Last updated 22 seconds ago
Customers say these underwear are extremely comfortable and feel like wearing nothing at all. They appreciate the no-show design that works well under tight clothing without visible panty lines. Users find them effective for light protection during periods, spotting, or minor bladder leaks, providing confidence throughout the day. Many mention the soft, smooth fabric quality. Common feedback includes sizing concerns, with several noting they run small and recommending sizing up. Some wish the absorbent area extended higher in the front for better coverage. While most praise the fit and comfort, a few experience side leakage or find the seams uncomfortable.

Christine V.Verified BuyerReviewingLight Leakproof No-Show Bikini - Rated 5 out of 5 stars2 weeks agoBest underwear ever!
I’m not using this for periods, but rather the after-the-kids-later-in-life issues. First of all, these are the most comfortable underwear I have ever worn and the leg openings feel like there is nothing there (I swear my varicose veins are better without the tension). (Large size was comfortable for my daughter and I and our weight ranges from 130-140lbs.) They are completely invisible panty lines too. Yesterday I walked 9 miles in them and never once had to readjust them because they stayed exactly where they should be and were very breathable. They do absorb well and prevent leaks to clothing as well as keeping odor free. It does feel slightly damp for about 15 minutes, but even if you press tissue against a wet pad, nothing will come up, the moisture is immediately locked in, so maybe it’s my brain fooling me. After about an hour the pad seems to dissipate the moisture and the pad is thin again and ready to absorb again. I would never have booked a 3-4 hour tour where I might not find a bathroom before. Amazing technology that I wish I had had growing up, but thankful I have it now!!
Amy G.Verified BuyerReviewingLight Leakproof No-Show Bikini - Rated 5 out of 5 stars2 weeks agoLove them!
I'm so glad I found this brand. I no longer have to purchase panty liners - they are comfortable and make me feel relaxed knowing they do what they are intended to do.
Natalia V.Verified BuyerReviewingLight Leakproof No-Show Bikini - Rated 5 out of 5 stars3 weeks agoSmooth and comfortable
I just ordered more to wear for hot weather or long travel days to help with wicking sweat as well as those I use for period days
