Rihanna may or may not have read CBS's Grammy fashion memo sent out to attendees and performers last week.
If she did, she was definitely pushing the envelope with her sheer red chiffon Azzedine Alaia gown that caused a few carpet reporters to admit that they had seen "a lot more of Rihanna than they should have" after she whisked by them.
Still, even with the slight nipple alert, her custom-made Alaia gown, Neil Lane jewelry and Manolo Blahnick shoes an effortlessly glamorous look that eerily coordinated with her on-again boyfriend Chris Brown's pure white (as in innocent, get it?) Lanvin suit.
So three years after having beaten Rihanna, the couple has reunited at the top music event. And If there's a message in their clothing, its that Rihanna doesn't mind wearing the Scarlet Letter and Brown is clearly wearing virginal white.
What do you think of Rihanna's sheer red gown?
