Garbiñe Muguruza steps out at San Sebastian International Film Festival

Garbiñe Muguruza looked at home on the red carpet at the recently-concluded San Sebastian International Film Festival, where she was on hand for the premiere of "Dance First," the biopic of Irish playwright Samuel Beckett.

Muguruza walked the premiere with her fiancé, Arthur Borges, and was styled in Dior. The former No. 1 rocked a look that wouldn't have been out of place on the silver screen: an elegant white dress with an asymmetrical neckline and long sleeve, paired with a mini bag and silver thread sandals.

"Dance First" closed out the official selection of the San Sebastian festival, which ran from Sept. 22 through 30.

Muguruza has been off the tour since February, announcing in April that she planned to take an extended break from competition. While she confirmed to Spanish publication Marca in July that her break is a "sabbatical" and not a "final goodbye," last month at a Zumba instructors’ event in Malaga, Spain, the two-time major champion kept mum with Spanish press regarding when she planned to return to the tour.

"I'm making plans that I couldn't make when I was still competing on the circuit," she said. “I only think about enjoying these holidays to the fullest, I haven't set any goals for myself yet."

In May, she and Borges announced their engagement, with plans to wed next year, and in July, Muguruza was nonetheless honored with Spain's Gold Medal for Sports Merit for her career achievements.
