When celebrities come dressed for the Grammys, pretty much anything goes — but this particular set erred on the side of ultraglam and impeccably chic. Beyoncé traded in her sexier Super Bowl fare for a polished black-and-white jumpsuit from Osman by Osman Yousefzada, and Girls' Allison Williams quite literally shimmered on the red carpet in a black, diamond-encrusted Kaufman Franco column gown. We were also pleasantly surprised to see Rihanna embrace a softer — but still jaw-dropping — look in a brilliant red Azzedine Alaïa gown, while Taylor Swift showed off a modern take on the Grecian-goddess look in a creamy J. Mendel confection. Click through for all the details on tonight's best-dressed contenders — then be sure to cast your vote!
