Who was Best-Dressed at the Grammys?


From Beyonce's stunning Michael Costello creation to Madonna's questionable tuxedo, our ET panel dissects the best and worst dressed at the Grammy Awards.

Beyonce seemed the unanimous winner of the night in terms of fashion, and designer Michael Costello shared the story behind the gown with Nancy O'Dell, Rocsi Diaz and Elle creative director Joe Zee.

"I had no idea she was going to wear the dress," said Costello, who admitted that he became discouraged when Beyonce performed in different outfit. "I was like, 'Ok, she didn't wear it.' Then moments later, there she is sitting next to Jay Z in the dress. I almost died."

There was some disagreement on our panel when it came to Madonna, who wore a tuxedo to match her son on the red carpet.

"I think that was awesome," said O'Dell. "What else was she going to wear and still match her son? What a great moment."

"I wasn't a fan of the tuxedo, but I thought it was cute that her and her son were matching," said Costello.
