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 2 months ago
Customers say these underwear are incredibly comfortable and feel like wearing nothing at all. Many appreciate the soft, butter-like fabric and 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, with many praising the confidence they provide for daily wear. Common feedback includes that they run small, with several reviewers recommending sizing up for better fit. Some mention the absorbent area could extend higher in the front for better coverage. While most love the comfort and functionality, a few note issues with side leakage or fabric breathability.

I bought a few pairs of these when I first got my period at 12, I am now 19 and I am just ready to replace them! They've lasted longer than any underwear and have been used every single period! They're definitely beat up now, but boy did I get my use out of them!

These are great. Perform as I expect. I haven’t tested them with the full tampon amount they are for, but that’s a personal preference, I haven’t had any issues for my needs.
