After a fabulous performance at Madison Square Garden in NYC for Z100’s Jingle Ball on Friday night, Ariana Grande flew out to Chicago, IL for yet another spectacular set for the B96 Pepsi Jingle Bash 2013 on Saturday (December 14th)! Ari wowed the crowd not only with her incredible vocals but the flashy red rhinestoned leotard and skirt she had on — perfect to catch all those lights and set the Christmas mood, we say! Not that she ever needs to be covered in rhinestones to shine once she hits the stage, that’s for sure.

Check out her new outfit in the gallery of performance pics from the Allstate Arena below:
