How to Measure

Waist

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 4 months ago
Customers say these French cut underwear are extremely comfortable and feel like wearing nothing. Many find the soft, smooth material creates no visible lines under clothing and stays in place throughout the day. The cut provides good coverage without riding up for most users, though some experience issues with the sides riding up or loose fit around the bottom. Reviews frequently mention the effective absorption capabilities, with users appreciating not needing panty liners anymore. Common feedback includes praise for the flattering fit and variety of colors, though some wish for more neutral color options. Several customers note ordering challenges with receiving different absorbency levels than requested.

ILIsabelle L.Verified BuyerReviewingLight Leakproof No-Show French Cut - Rated 5 out of 5 stars1 week agoAmazing
I wanted underwear that could help with the occasional leak. These tick all the boxes.
SCSabine C.Verified BuyerReviewingLight Leakproof No-Show French Cut - Last Call - Rated 1 out of 5 stars1 week agoRide so high
I had to use two hands to pull down. Again and again. I wore them for less than two hours before I took them off.
SSstephanie s.Verified BuyerReviewingLight Leakproof No-Show French Cut - Rated 5 out of 5 stars2 weeks agoThe only underwear I buy!!
I absolutely love these! My only complaint is that Knox doesn’t have them in all colours that their bras are in so I feel limited to bra selection that match these specific panties….but I do because that’s how much I love these panties! I love that I can wear them and not worry if my tampon leaks, I love that I can wear them and not worry if my period starts in the middle of the night, I especially love that the cut is sexy but still comes up to my belly button - c-section x2 mum here! I’ve got that pooch that will never go away and I don’t really love it hanging over my undies, this cut holds it all in without the high waist super low leg style - which I bought once and just did not feel like a sexy young woman, I felt like I was wearing my mum’s panties and she’s 67!! 😂
They’re fantastic, to the point that I don’t own any panties except the French Cut in Light and Medium Leakproof No Show.
MMelissaVerified ReviewerReviewingLight Leakproof No-Show French Cut - Rated 5 out of 5 stars2 weeks agoAn Excellent Purchase!
Style, fit, and quality are exceptional!
Thank you, Knix!
VMVictoria M.Verified BuyerReviewingLight Leakproof No-Show French Cut - Last Call - Rated 5 out of 5 stars3 weeks agoanother winner
For many years I have worn Knix bikinis and been delighted. On a whim, I chose the French cut to refresh my stack of underwear. I love them! My new favorite. At 80 years old, I appreciate the full coverage of my tummy and the French cut lengthens my legs. Ooohlala!
KTKathleen T.Verified BuyerReviewingLight Leakproof No-Show French Cut - Rated 5 out of 5 stars1 month agoGreat product
I tried the other seller,s product but the fit was not comfortable
I purchased this product Knix and the fit was perfect
Had enough stretch in the legs that your circulation wasn’t being cut off
This is the only make Knix I will buy

BBBarbara B.Verified BuyerReviewingLight Leakproof No-Show French Cut - Rated 5 out of 5 stars2 months agoPerfect fit!
“Light” is just the right amount of protection for post menopausal me! I’ve been wearing Knix for a year now and go against the rules by washing on warm and throwing in the dryer and I’ve had no issue with their quality. Great product and I’m now a loyal customer!
KKnix2 months agoHey Debb!
This is amazing! We're so happy the Light protection level is perfect for you and that you're loving the quality. Thanks for being such a loyal customer!
