SPANX Higher Power New & Slimproved Hook & Eye closure Let's just say the savvy women at SPANX took Power Panties and extended the control above the waistline -- all the way up to just the south of the "twin peaks." SPANX Higher Power eliminates VPL (Visible Panty Lines) and slims, smoothes and shapes the figure from the lower thighs up through the midriff. Plus, there's no binding legband to create bulge on your thigh! Soft hosiery fabric has a flat seam up the front and back. Not recommended for thin or clingy fabrics.
