I am sorry that so many people are dissatisfied with the Kymora Body Shaper. A professional fitter recommended it to me because I needed a good uplifting bra plus support around the middle. An all-in-one body shaper will sometimes pull your bust down if it isn't long enough in the body, but the Kymora doesn't because you use your own bra with it.
The first time it was a little difficult to get on but after that I found it quite easy and it definitely does pull me in and make me stand up straighter. My advice is to make sure you buy the right size and that will probably make it a lot easier.
I have since bought another one in Wal-Mart in the "As Seen on TV" section so that shows that I like it and will continue to wear it.
