Jannik Sinner steps out with Jin, Kirsten Dunst and more at Gucci's Milan Fashion Week show

After passing up the opportunity to compete in his first-ever Laver Cup, world No. 1 Jannik Sinner was in a different kind of spotlight this week as he sat front row at Gucci's Milan Fashion Week show.

The Italian luxury brand has sponsored the world No. 1 since 2022, not only providing him with a trademark equipment bag that he's carried on court, but also dressing him for a stylish *Vogue* magazine profile this spring.

But in Milan, which showcased the brand's spring and summer 2025 collections, the US Open champion looked relaxed, cool and crisp in a black jacket and trousers, an olive green polo shirt, and white Nike sneakers. He rubbed shoulders with K-pop star Jin, actress Kirsten Dunst, and other celebrities, as well as fashion mogul and Vogue editor-in-chief Anna Wintour.

Sinner wasn't the only player to trade forehands for high fashion this week. Before heading to Laver Cup in Berlin as one of the leading members of Team World, American Taylor Fritz linked up with Sinner's countryman, Matteo Berrettini, to walk the runway for their mutual sponsor Hugo Boss. And across Europe in London, US Open semifinalist Jack Draper was also seated in the front row for Burberry's summer 2025 show at that city's Fashion Week.

But the fashion house's show was just one part of the world No. 1's stacked weekend in Milan, which also saw him named an ambassador for the 2026 Winter Olympics in his home country. Sinner, once a high-level junior skier, is set to be the face of Team26, the initiative aiming to recruit the 18,000 volunteers needed for the Games.

"The 2026 Milan Cortina Olympics and Paralympics will be held in places that are very special to me," he said in a press conference, per Italian media. "I grew up in one of the most beautiful parts of Italy, our mountains are a marvel. Skiing for me is like walking. It is a great honor to be part of these Olympics."
