Spanx's French rib fabric, in both sweats and a matching cardigan, has been introduced as a new model of the brand's wide-leg sweatpants. The new model features thicker fabric, less pilling, and roomy pockets. These are now some of the only sweatpants I wear out of the house and have become my favorite Spanx pieces. While these particular styles are not discounted, other spring pieces are up to 72 percent off. The retailer's French Rib fabric is now available for over half of the price.
