    Just 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.

    It’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.

    A 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.

    Great 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.

    Love the product

    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.

    Do love all my knix products.
