So this might be a silly question, but I just want to know does Spanx actually work or is it a waste of money? I love my dress except that I am not happy with a bit of lower belly pooch, and while I am trying to lose some weight I don't wan't be that bride who wakes up on her wedding morning, not have lost any weight and getting upset with belly pooch. So is it worth it? Does it actually flatten your belly or is it a $100 waste?
