Tennis champion Serena Williams swapped the court for the runway as she strutted her stuff for the Vogue World show at New York Fashion Week on Monday.

The former world No.1 turned heads in a metallic dress and cape as she joined the likes of Gigi Hadid on the catwalk.

The newly-retired athlete, 40, was then seen sitting front at the show next to Vogue’s famed editor-in-chief Anna Wintour, 72.

For the show, held in the city’s Meatpacking District, Serena wore a skintight silver dress and matching cape that was buttoned up at the neck.

Her look was completed with a pair of silver heels and oversized silver jewel earrings.

Her dark locks were tied back and off her face into long ponytail and her makeup was completed with a glossy nude lip.

Serena looked nothing short of confident as she strutted down the runway in front of packed audience.

In a nod to her tennis roots, young children in tennis outfits walked down the runway alongside her holding rackets.

Off the runway, Gigi Hadid, 27, held hands with Serena as the close friends walked backstage.

Gigi looked chic in a pair of baggy denim jeans and a white singlet with a metallic net top.

Gigi and Serena are close friends, with the model revealing on Jimmy Fallon earlier this month that the pair enjoy wild karaoke nights together.

Gigi also put on a very animated display while supporting Serena at the US Open on September 1, alongside her sister Bella.
