The article I read suggests Spanx. I have not ventured into the world of shapers just yet, but I've heard over and over that Spanx is the next best thing to doing nonstop crunches.
On a similar note, I ventured to Sears (yes, the one that has 12 ghetto taco carts parked outside) on Saturday. They sell Dr. Rey (from Dr. 90210) brand shapers. Prices were reasonable.
Next, the last, but not least, essential.
