Naomi Osaka’s most recent sea creature-inspired outfit turned heads, but making statements through style is nothing new for her. From protest masks to high-fashion collaborations, she transforms the tennis court into a canvas, blending identity, activism, and innovation in every look.
Although her sea creature-inspired outfit debut caught eyes at the 2026 Australian Open earlier this month, Osaka is no stranger to making statements through style. Whether she’s nodding to high fashion or signaling something more political, the four-time Grand Slam champion treats the court as both arena and runway.
And that makes her bold choices all the more striking in a sport steeped in tradition.
History of all-white rule
For centuries, tennis enforced a single, unwavering dress code: white. The custom dates back to the 16th century, when French aristocrats played a similar sport to modern tennis known as jeu de paume. At a time when people considered visible sweat improper, they favored white garments because they could disguise it, which is a practical choice that soon became an enduring symbol of refinement and decorum.
Over time, the all-white standard became synonymous with tennis itself, embodying the sport’s genteel roots and polished image. Which is precisely why players like Osaka, who infuse the game with personality, cultural commentary, and fearless fashion, feel so modern. In a sport once defined by restraint, self-expression is becoming its own tradition. Today, Wimbledon is the only tournament that still requires the traditional white dress code.
Tennis fashion hasn’t always been as neutral as it appears. The sport’s rigid devotion to the country-club roots has reinforced narrow ideas of who belongs on the court. From scrutiny over hair beads and women’s emotions on the court, dress codes and the sport standards have disproportionately policed those who challenge its traditional image.
In context, fashion becomes more than a style choice, becoming a quiet assertion of autonomy and a way of expanding who gets to define tennis tradition.
Osaka’s style evolution
Osaka’s fashion arc reads less like experimentation and more like an intentional, precise path that unfolds over time. Earlier in her career, when Adidas sponsored her, Osaka debuted clean silhouettes, bold colors, and subtle individualities within the boundaries of tournament expectations. But even then, there were still the intimate details like playful prints and her usage of color. However, in 2019, she made the switch over to Nike and has continued to be a fashion icon since.
As Vogue noted in its roundup from 2020, “5 Times Naomi Osaka Has Used Style to Make a Statement,” her outfits have carried meaning time and time again – from masks reading the names of victims of racial violence to silhouettes that challenged tennis orthodoxy. Each appearance has an intention in what’s being illustrated and what statement is being made.
Now, whether she’s channeling sea creatures or large bows on the back of her skirt, Osaka’s aesthetic feels cohesive. It’s bold but measured, expressive yet strategic. This isn’t trend-hopping. It’s authorship, a carefully constructed identity that evolves, but never wavers. However, Osaka’s style isn’t just about the spectacle or silhouettes, but is used for advocacy and functioning as almost a language.
Fashion Used For Advocacy
The 2020 U.S. Open showcased this. While others focused on making sure the event was managed safely, as the pandemic had hit hard just earlier in the year, Osaka prioritized honoring the victims of racial discrimination and police brutality, including George Floyd, Breonna Taylor, Ahmaud Arbery, and more. After each round of this tournament, Osaka changed her mask to honor another.
In an interview with Vogue in 2020, Osaka expressed, “I’m aware that tennis is watched all over the world, and maybe there is someone who doesn’t know Breonna Taylor’s story.” It’s one example of how Osaka uses her platform and visibility to share a story that may have been ignored.
In a sport that has historically encouraged neutrality and where athletes, particularly Black women, often face backlash for overt political speech, Osaka found a form of expression that could not be interrupted mid-sentence. The masks said what press conferences sometimes cannot. They also reframed the athlete-media dynamic. Rather than reacting to questions, she was able to control her own narrative.
In doing so, Osaka expanded the conversation beyond race to include mental health and scrutiny – reminding the world that silence, too, can be strategic.
Identity, heritage, and self-definition
If the masks made clear that Osaka understands the power of visibility, her broader fashion narrative reveals something a little more intimate, which is her expression of her own cultural heritage. Beyond protest, her style has become a canvas for her identity. Born to a Haitian father and Japanese mother, Osaka has paid tribute to her cultural background on the court.
At the 2024 U.S. Open, Osaka stunned spectators not only with her talent in the sport but also with her outfit.
Designed by Yoon Ahn in collaboration with Nike, the design featured elements like ruffles, tulle details, and of course – the big beautiful bows.
“The inspiration for me was definitely Japanese, like Harajuku,” said Osaka in an interview with the New York Times. “I remember one of the first times I went to Japan, I saw so many frills and so many bows.”
The designer also featured a black version of the outfit, making Osaka feel, in her words, like a “black panther.” Even her subtle outfits are symbolic and quietly assert that identity is constructed, not assigned.
Redefining Endorsements: Athlete to Creator
When sponsored by a specific company in the sports world, it can be hard to stick out as having your self-authored narrative instead of plain branding. However, Osaka has mastered both her narrative and branding through working with Nike.
For decades, athlete endorsements have followed a familiar script: a logo on the chest, a signature shoe, a campaign built around performance. The brand creates; the athlete wears. Osaka’s partnership with Nike suggests a different model, one rooted in collaboration rather than simple sponsorship. She actively shapes her on-court looks, infusing them with narrative, cultural references, and personal symbolism instead of treating them as interchangeable uniforms.
For example, Osaka and Yoon Ahn collaborated to create the outfit for the 2024 U.S. Open, and Nike orchestrated the partnership. Nike isn’t giving Osaka an outfit to wear without any say, but is actually connecting her to designers and artists that can help bring her vision to life. The same thing applied to her most current showstopper – her exoskeleton 2026 Australian Open outfit.
In a recent interview with Vogue, Osaka expressed how she felt about the opportunity she had to create the eye-catching outfit.
“So much of the time, other people get to write our stories for us. This felt like a moment where I could write a little bit of my own,” the athlete said.
Contrasting with her inspiration for the iconic bow outfit, Osaka had her light bulb moment when she was reading to her daughter.
Osaka’s Newest Creation
“There was an image of a jellyfish, and when I showed it to her, she got so excited,” she said in an article with Vogue.
The look, designed by Robert Wun, incorporated sea creature themes with the tie-dye turquoise and flowing tendrils over the seams, evoking the fluidity and movement of ocean currents. Designers carefully considered accessories and styling to complement the aquatic motif, reinforcing the narrative without overshadowing performance. The ensemble wasn’t just clothing, but a blending of fashion and a visual narrative – one authentic to Osaka.
What sets this outfit apart from the rest? It’s not just that it may be her most intricate look yet, but that it’s now accessible beyond the court, as Nike is now selling it through their online store. Through her partnership with Nike, Osaka’s vision moves from personal expression to shared experience, allowing fans to participate in her narrative and literally step into her style.
By transforming her performance attire into wearable fashion, she extends the impact of her design beyond symbolism, blending creativity, advocacy, and commerce.
In redefining what it means to dress for the game, Osaka isn’t just making a statement with her style; she’s making the sport itself more fluid, more inclusive, and more imaginative. Tennis, once rigid and uniform, now bends to her vision and, in doing so, opens the court to anyone who dares to play and dress on their own terms.
