CBS Standards and Practices sent guests and presenters a detailed email, obtained by Deadline.com, outlining in excruciating detail as to what must be covered, including "bare fleshy under curves of the buttocks and buttock crack" and "[b]are sides or under curvature of the breasts."
There was also a ban on "sheer see-through clothing that could possibly expose female breast nipples."
The stars, however, didn’t seem to pay the new rules any mind. Katy was busting out of a body-hugging mint green gown with a perfectly placed cleavage-baring cutout, while Rihanna hit the red carpet bra-less in a racy red dress. Kelly Rowland left little to the imagination in a full-length black Pucci gown made of sheer paneling and little else.
Other head-turners included Beyoncé in a skintight black and white getup, and Jennifer Lopez in a black gown perfect for leg bombing.

There was supposed to be a Grammys dress code this year, but apparently no one -- including Katy Perry, Rihanna and Kelly Rowland -- got the memo!
