Beyonce runs the world in Rubin Singer

She put a relatively unknown designer on the world's stage Sunday evening.

The leather concoction Beyonce was immortalized in during her Super Bowl performance was the result of hours of hard work by designer Rubin Singer. "It's the biggest moment of my career," he told New York Times fashion critic Cathy Horyn who shared a sketch of Bey's costume via social media as soon as the artist took to the stage. A favorite of Beyonce when it comes to stage matters, Singer also designed the looks for Beyonce's 120 backup dancers and Michelle Williams. Kelly Rowland wore Emilio Pucci.

By the numbers, it took 2 months of planning, 5 fittings, 14 workers and over 200 hours of labor to complete the costume comprised of a black leather bodysuit, motorcycle jacket and skirt. The New York-based designer was also backstage Sunday evening to ensure that "everything was perfect for the big night," he stated in the release.

In January, Singer affectionately shared with Glamour, the Knowles sisters are "the only celebrities that always dry clean and send clothes back in a box, with a hand-written thank you note."
