CBS is not taking any chances on a wardrobe malfunction at Sunday’s Grammy Awards. The network fired off a letter to the “talent” appearing on the show, advising them not to wear anything risqué to the ceremony. "Please be sure that buttocks and female breasts are adequately covered," it reads. "Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack." It continues, “Bare sides or under curvature of the breasts is also problematic. Please avoid sheer see-through clothing that could possibly expose female breast nipples. Please be sure the genital region is adequately covered so that there is no visible 'puffy' bare skin exposure.” In addition, the network does not want the stars to wear any lapel pins with the name of an organization “visibly spelled out.” That means they can wear a colored ribbon to support a cause, as long as that cause isn’t clearly written on it.
