Becky Worley reviews infomercials for ABC. Here's her thoughts on the 'invisible tummy trimmer'. (No, she is not wearing it in the photo above.)
At first, I wasn't very impressed with the Tummy Trimmer. It's a tubular girdle, and as a result it doesn't stay in place very well. It slides up along the bottom, creating some unsightly rolls around the beer-gut area. Also, it promises to work on back fat -- which it does, but it also creates a weird roll at the top of your back where the girdle ends. If you want to be serious about flattening and tightening like this, you need Spanx or a girdle that has a mechanism to stay in place. But keep in mind those cost considerably more than the $20 that the tummy trimmer costs.
The saving grace for the Tummy Trimmer came when I found a pretty cool way to use it: I wore it over the top of my jeans, where it helped to rein in my muffin top by streamlining the transition zone from tight jeans to loose hip flab.
