There was supposed to be a Grammys dress code this year, but it looks like the stars like Katy Perry, Rihanna and Kelly Rowland didn't follow the guidelines! CBS Standards and Practices had sent guests and presenters a detailed email 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.
