Stewart was honored with the Stylist of the Year award and Roberts was named Style Icon at the event held at the Getty Center. They wore matching gray pantsuits.

"It was not a faux pas. To twin it is to win it," Roberts said.

"She had this brilliant idea. We were flying home from a job on a plane and she said, why don't we dress the same? I was like, OK! So there you go," Stewart said. "Twinning is winning."
