Most court cases start with one side accusing another of wrongdoing. Fashion’s latest legal challenge starts a bit differently. Spanx, the shapewear company founded by Sara Blakely in 2000, received a demand from Yummie Tummie, a shapewear company founded in 2008 by Real Housewives of New York City star Heather Thomson, to stop selling their Total Taming Tank and Top This Cami. Yummie Tummie believed those two products infringed on patents for their signature shapewear.
