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.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 3 months ago
Customers say these period underwear are comfortable and provide excellent protection without the bulkiness of traditional pads. Many appreciate the thin, no-show design that works well under clothing and the stylish patterns like polka dots. Users frequently mention the confidence and peace of mind these provide during periods, workouts, and daily activities. Several note they're particularly good for teens and lighter flow days. However, common concerns include sizing inconsistencies, with many finding recent purchases run smaller than expected. Some mention the front coverage could be longer, and a few experience issues with leg holes being too tight. Despite sizing challenges, most customers praise the comfort, absorbency, and quality of the product.

RReaReviewingLeakproof UltraThin No-Show Bikini - Last Call - Rated 4 out of 5 stars1 week agoGreat leakproof
I wear them for light bladder leaks. Menopausal so no more periods. They work really well for that purpose. They are also no-show. The only issue I have is they don’t stay in place as well as I would like. I am unfortunately getting some wedgies with loose clothing.

JMJude M.Verified BuyerReviewingLeakproof UltraThin No-Show Bikini - Last Call - Rated 5 out of 5 stars2 weeks agoLeakproof backup
I use these alone some days and other days as backup. They usually last a year or more depending on whether I dry them a lot or hang them to dry.
ARAshley R.Verified BuyerReviewingLeakproof UltraThin No-Show Bikini 3-Pack - Last Call - Rated 2 out of 5 stars2 weeks agoSizing
These fit smaller than the bikinis in cotten or the briefs. They squeeze my body. Maybe sized wrong? Cotten one is underneath. Maybe I’ll loose weight?
