A new tint releases almost every time Osaka takes center court. Sunflower Yellow hit shelves in January 2025, when she competed at the Australian Open. In May 2025, the Pink Foam version dropped after the French Open. And now, the hard court crimson version is available for $170.

Nike also provided its ambassador with brand-new shoes, as the brand have since she signed on in 2019. She sported the GP Challenge 1 "Naomi Osaka" sneakers in the Picante Red/Bright Crimson colorway. This is the fourth addition to the circa-2024 launch, following Black, Sunflower Yellow, and Pink Foam.

Naomi Osaka brought a bevy of sparkle and floral inspiration to her 2025 U.S. Open first round match against Greet Minnen of Belgium, wearing a custom red rose Nike kit with a matching Labubu for Tuesday night in New York City’s Flushing Meadows.

Gauff and Osaka are just two of the several players who have been spotted wearing on-court apparel in striking red: Marta Kostyuk and Alycia Parks in Wilson, Frances Tiafoe in Lululemon, Alex Eala and Emma Raducanu in Nike, to name a few.

Bringing her signature style to clay, Naomi Osaka stunned the Paris Slam with her baby pink, halterneck dress inspired by the cherry blossoms or the Sakura of Japan, which was outlined with maroon accents. She used the maroon in more elements of her outfit, like her visor and wristband, to make her dress pop.
