Naomi Osaka teases more iconic tennis kits: 'Treating every Grand Slam like the Met Gala'

Naomi Osaka is itching to serve up more style in 2025. The four-time Grand Slam singles champion revisited some of her most iconic on-court outfits in a look book to her Instagram story on Thursday, writing on the companion app Threads that she treats "every Grand Slam like the Met Gala"—while teasing more to come.

The four-time major champion, who has been with Nike since 2019 and boasts her own line, is also known for her custom looks designed in collaboration with the sportswear giant. Some of the kits that Osaka flashed back to included the orange-and-black pleated dress designed in collaboration with Japanese luxury brand Sacai she wore to defend her first Grand Slam title at the 2019 US Open; her national kit for the 2021 Tokyo Olympics, complete with red-and-white braids; and her 2024 Roland Garros dress, a high-neck, asymmetrical black number with a white underskirt, which she called "underrated."

The crown jewel that "reigns supreme," Osaka wrote, was the head-turning Yoon Ahn dress she wore in two colorways during last year's US Open, which came in day (green) and night (black) editions and featured a statement-making bow at the back.

And move over, New York Fashion Week: She told followers that Arthur Ashe Stadium might once again be her own personal runway this summer.

"This year's US Open might be coming for her spot, though," she wrote, with a blushing emoji.

Osaka also gave love to her footwear, stating that her "shoe game is debatably more lethal" than her sartorial stylings, calling out the Haitian-inspired camoflague sneakers she wore on the way to winning the 2021 Australian Open, the US Open shoes she wore later that year dedicated to her parents' respective homelands; and the sunflower-inspiried motifs that featured in her 2025 Melbourne wardrobe.

Osaka then proceeded asked fans to predict what blossom would inspire her next major outfit, and though she gave no clues, her audience chimed in with a wide-ranging opinions, from springtime's favorite tulips and sakura cherry blossoms, to hibiscus, Haiti's national flower.
