Beyoncé Knowles certainly brought her Sasha Fierce alter-ego for her half-time performance at today's Super Bowl game in New Orleans. The sexy songstress wowed the crowd with her all-hit repertoire (including "Love On Top", "Single Ladies", "Crazy In Love" — with some help from Destiny's Child pals Michelle Williams and an Emilio Pucci-clad Kelly Rowland), but it was her scene-stealing costume that got, and held, our attention. It have even topped Madonna's Givenchy number from last year's half-time show. The new mum wore a structured leather leotard designed by long-time costume collaborator Rubin Singer, which featured quilted straps and a lace cut-work mini-peplum-cum-skirt. Nude fishnet stockings, knee-high socks, solid lace-up Proenza Schouler ankle boots (which look like a leather version of these suede puppies), elbow-length gloves and a gold mani added just the right dose drama. If you didn't see her in action, we suggest you step on in and take a closer look at Sasha's, er, Beyoncé's killer costume plus the original sketch by the designer.
