Season 9 of “The Voice” moved on to the knockout rounds. And speaking of knockouts, Rihanna was on hand, wearing a fetching denim combo to pitch in as a “key adviser” to all the coaches.

Rihanna rocked a denim-on-denim ensemble by Marques’Almeida which included a frayed bustier and cropped jeans. She dressed up the day-time duds with Manolo Blahnik’s pretty pearl ankle-strap Chao sandals and a pearl necklace.

And Rihanna was not the only “denim queen” present, almost everybody else in this video was one way or the other clad in denim as well!

Marques Almeida denim is available at Shopbop.
