- Rated 1 out of 5 stars2 months agoHigh Rise Brief
Not true to size . Coud not put them on because there was no give. Would not stretch at all!
Karen Y.Verified BuyerWas this helpful? - Rated 5 out of 5 stars3 months agoJust what I needed!
I might be 10 pounds thinner tomorrow if a magician has a magic wand, but absent that, these do the trick. They firm up my stomach area and leave no vpl.
Rosalind M.Verified BuyerWas this helpful? - Rated 4 out of 5 stars4 months agoIt’s was ok
I might have gotten the wrong size because it keeps riding up. I wrote 4 stars as return process was real easy and I exchanged it for another style instead.

Love!
KeshiaVerified BuyerWas this helpful? - Rated 4 out of 5 stars5 months agoA little long
I bought the size according to my measurements and found the product a little too long in the waist area. I am rather short waisted so I don’t consider this to be a fault of the product, but maybe Knix could look at petite sizing for items like this.
Otherwise, this item does the job. Keeps all the bits tucked in and looking smooth.

very comfortable
Diane S.Verified BuyerWas this helpful? - Rated 5 out of 5 stars7 months agoGreat support
Really enjoyed the fit, the way it tucked it all in and smoothed everything out. Most importantly, they stayed in place and did not roll down like other brands.

Yes, I did receive my new Shaper High Raise Knix and the XL fits much better. I gave my L Shaper High Raise Knix to a family member.
