Does anyone know anything about the Spanx products? I first heard about them on the Oprah show and am wondering if they are as good as they say they are. I have my eye on one that is supposed to pull in your tummy and lift your rear. Also, they want to know my measurements. I hope they won't send me something that will fit my measurements now and won't pull or lift anything. I ask the clerk in the undergarment department of Macy's about the measuring thingy and she said she didn't know. Big help she was.
