The Grammys may be the biggest night in music, but as a fashion show, it ain't too shabby either. Especially when you have couture all-stars like Rihanna, Katy Perry, and Beyoncé rocking the red carpet.
Which—you saw it—they did.
Adele's voluminous Valentino had tongues wagging, too, early in the night, while Ri-Ri stunned in a floor-length scarlet number by Alaia.
Beyoncé raised eyebrows by forgoing her usual skirts and dresses in favor of a pantsuit by Osman. Katy Perry let it all hang out—almost!—thanks to a keyhole-cut Gucci, and Jennifer Lopez flashed some Jolie-level gam...via a very, very high-cut Zuhair Murad.
So who was a hit and who flopped?
