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.

These are an upgrade of Knix for me...I am actually a small not a medium so enjoy the smooth fit of these!
HYHeather Y.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Rated 5 out of 5 stars9 hours agoHigh rise pack
Good price for 3 pair.
I bought XL, as usual, but found them more “ snug” than others I recently bought. Different factory, different cutters at the machines?
They are not uncomfortable, just mentioning the difference in case other people find similar situation.
