Naomi Osaka promised the world that her return to the US Open would feature “the best outfit” she’s ever worn—and, damn, did she deliver. This year, she’s hitting the court covered in bows (on the back of her bomber jacket, tennis dress, and even her shoes). But this bold, playful look isn’t just about style—it’s also part of her mental game.

Since returning to the tour from maternity leave, the four-time Grand Slam champ has been open about the challenges of performing the way she used to, and fashion is one way she boosts her confidence during competitions. “When I wear what I feel is a good outfit, I definitely feel more comfortable,” Osaka said in a New York Times interview published Sunday.

More specifically, her girly, coquette theme is actually a nod to her Japanese heritage (“like Harajuku,” she added). “I remember one of the first times I went to Japan, I saw so many frills and so many bows,” Osaka said. “I wouldn’t automatically associate myself with being girlish when I’m on the court, but I tend to gravitate toward really beautiful and cute things. I think there’s something quite cool in making that an emphasis.”

Beyond just looking stylish (or as Osaka herself joked, “very mindful, very cutesy”), the dainty ribbons also symbolize her graceful yet powerful playing style on the court. “Actually, my movement coach is a ballerina. She’s also my mental coach,” she added. “Before I met her, I thought ballerinas were just flexible, but then I realized they’re all incredibly strong.”

This also explains why she decided to go with two custom-made designs by Nike for this tournament: One green ensemble for daytime matches, and another black one for nighttime competition. “[The color green] gives me peace and serenity,” Osaka explained. “I think colors give you power.” As for black, that gives her strength: “I feel a little bit like Black Panther.”

Even though Osaka knows she’s under the spotlight for her highly anticipated return, she’s embracing the moment: “When I put on my US Open outfit, I’m going to feel a transformation,” she said—and that change includes “letting go of the expectations I put on myself.”
