I found the shaper top in black in size XXL at Big Lots for $15 and I paid less with a 20% discount.  I wriggled it on at home by stepping into it (I had to basically roll it around my hips and tug it up gradually and gently from side to side) as in the instructions.  It was fairly comfortable and it seemed to slim down my waist and abdomen, but I was dismayed to see that it did nothing for my back fat other than relocate it.  I was wearing a bra with it.  I have decided to hold on to it and try it with several bras to come up with the best combination since it is fairly comfortable and true to size.
For those who were wondering, the product doesn't seem to have much stretch to it.  It is a fairly tight compression type mesh fabric with front lining at the abdomen and criss-cross construction across the back.  It is a bit difficult to put on - definitely wait to put on anti-perspirant until you have managed to get this top on otherwise you will end up with antiperspirant all over the top and none under your arms!  BigLots had this top in three sizes, I believe - XL, XXL and XXXL.  I only wish that I could find it in beige!  Happy Shaping!
