    Fit the bill!

    I needed something that would work under a beautiful new pantsuit I had purchased, yet not show my panty line! Anything I had at home just didn’t work! These were perfect, comfortable and provided great tummy coverage too. This colour was great under black as anything black showed through a bit. I ended up going with a Large, same size as most of my other Knix pieces.

    I use it as a shaper, it works great.

    I need back support after recent pain and it really helped me.

    so-so

    I bought two sizes, and neither was a perfect fit. The shaper was a little stiff and for the price, I can find better shapewear. The leakproof gusset was fine but not worth the high price.

    High-rise rolls down

    High-rise doesn’t stay up for me when sitting.

    Works very well!

    I put these on and immediately was like “holy moly I am snatched!” They work so well! They are the first pair of shape wear that haven’t rolled down on me. Will definitely be buying more.

    Shapes well but rolls down

    I don’t find these very secure at the top. They roll down very easily and need constant adjusting.

    Customer service & products are great

    I was able to chat with Robert about my orders and rewards and was given great advice. Your products are worth the cost but when there’s a sale I love them even more!
