Did you know that Target has a brand called ASSETS that is similar to Spanx, at half the price?
Macys also carries the Flexees brand of shapewear, which come in a variety of colors and sizes. This brand is lightweight yet gives firm control. (For an added discount shop during a Macy's one day sale!)
Another great place to pick up body shapers is the Bali outlet at the Prime Outlets. I suggest you visit the Bali web site's fit calculator to learn more about the products before heading to the outlet.
One last tip: remember to try on a variety of brands and styles to find the one that is right for YOU.
