She lost the US Open, but won big at Fashion Week.

Serena Williams bowed her second collection to a crowd that included rumored boyfriend Drake, Anna Wintour and Gigi Hadid — but she’s still more comfortable on the tennis court than the runway.

“[Tennis], that I know I can handle,” she said. “Fashion? With all of the critics? We’ll see how it goes.”

Luckily, she has a fairy godmother in Vogue editor Wintour, who has been showing her the fashion ropes.

“Anna’s really been my mentor,” Williams said. “She’s gone over this whole collection.”

As for how athlete-turned-designer balances it all, she joked “I don’t sleep, so that helps.”

Her collection of fringed dresses, tailored blazers and cleavage-baring tops was available immediately on HSN.
