After CBS issued a "Wardrobe Advisory" spelling out just what the network 's big-wigs consider inappropriate to wear on national television (wardrobe malfunctions may be good for ratings, but they're not so popular with the FCC), many celebs undoubtedly had to go back and rethink their Grammy red carpet looks, or ... not!
Rihanna showed up in a red Azzedine Alaia gown that, at certain moments, made us press our faces up right up to the TV and ask "My God, Ryan Seacrest, are those Rihanna's nipples?" Ri-Ri then changed into a decidedly under-boob revealing crop top and skirt for her performance. Katy Perry's Gucci gown looked like it was barely holding her in, but it's Kelly Rowland who wins the award for most in-your-face naked.
Take another look at the guidelines CBS issued below, and then decide for yourself what was the most controversial in our slideshow.
Please avoid exposing bare fleshy under curves of the buttocks and buttock crack. 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.
