Four-time Grand Slam champion Naomi Osaka plays in the U.S. Open quarterfinals tonight, and her Nike outfit will be glittering under the lights of Arthur Ashe Stadium.

Osaka has worn two different versions of her kit this year: a red version, for the night session, and a lilac one, for day session matches.

After her first round match, Osaka revealed, “I designed this outfit a while ago. We tried it on, honestly, last year. It was really elaborate, because the crystals are really hard to do on a performance outfit. I just thought it would be really fun to do a New York under the lights. I’m glad that my first match was a night match, because this outfit was really fun to play [in].”

As she mentioned, the outfit is a tribute to New York City; during the tournament, Osaka posted on Instagram, “Nothing beats playing at home.” Osaka, 27, was born in Chūō-ku, Osaka, Japan, but moved to the U.S. when she was three years old, and grew up in Queens, New York.

Osaka’s hair during her first round match at the 2025 U.S. Open featured small roses.

Of the roses in her hair for her first U.S. Open debut, Osaka told reporters, laughing, “My hair was a little chaotic. I just sent Marty, like, hair inspo maybe a week or so ago with a big ponytail with roses in it. I was, like, Do you think this is possible? Maybe it was two weeks ago. Yeah, we kind of just toss ideas around. Obviously the outcome is way better than I could have imagined.”

At the U.S. Open, in addition to hair jewels, she’s also had a special accessory: For each match, Osaka has brought a blinged-out, custom Labubu attached to her racket bag.

“Honestly, I’m not a Labubu collector,” Osaka said after her second round match. “This is kind of like a one-time thing for the tournament. Honestly, it kind of started as a joke, so I’m glad people are liking it.”

Each Labubu has had a different name after a tennis great: “Bille Jean Bling,” “Arthur Flashe,” “La-Billie-Bu,” and “Althea Glitterson.”
