Four-time Grand Slam champion Naomi Osaka has once again merged high fashion with elite athletics, debuting a custom "jellyfish-inspired" kit during the opening rounds of the 2026 Australian Open.
The outfit, a collaboration between Nike and London-based designer Robert Wun, immediately went viral following the world No. 17's first-round victory over Croatia's Antonia Ružić.
The avant-garde walk-on look featured a turquoise and green tie-dye palette, characterized by organic, wavy ruffles designed to mimic the movement of jellyfish tentacles. The multi-piece configuration included a zip-up jacket with cascading tendrils, a pleated miniskirt layered over wide-leg trousers, and a dramatic wide-brimmed hat complete with a sheer white veil and matching parasol.
Osaka later revealed her two-year-old daughter Shai inspired the concept. While reading a marine life storybook together, Osaka noticed her daughter's interest in a jellyfish illustration. That led her to translate the visual into her 2026 tournament aesthetic.
"It felt symbolic of energy, transformation, and excitement," Osaka told reporters. She went on to describe the design as representing "the birth of something new" in both her career and journey as a mother.
The outfit also featured two delicate white butterflies — one fixed to her hat and another to her parasol. These served as a reference to the 2021 Australian Open, when a butterfly famously landed on Osaka’s face during her title-winning run.
On the court, Osaka has backed the bold style with strong performances. She secured a 6-3, 3-6, 6-4 win over Antonia Ružić in her opening match on January 20th, followed by a hard-fought 6-3, 4-6, 6-2 victory against Sorana Cirstea on January 22nd.

Naomi Osaka advanced to the third round of the 2026 Australian Open with a three-set victory over Sorana Cirstea on Thursday.
But the hard-fought win was overshadowed by a heated exchange at the net and a subsequent public apology from the former Japanese fan favorite.
After Osaka defeated the unseeded 35-year-old 6-3, 4-6, 6-2 at Margaret Court Arena, the two shared a tense handshake before Cirstea reportedly called Osaka out for her on-court conduct. The issue apparently centered on Osaka’s habit of shouting "Come on!" to celebrate points, specifically between Cirstea’s first and second serves — a move the Romanian considered both a distraction and a breach of sportsmanship.
In her immediate postmatch interview, Osaka dismissed Cirstea's complaints.
"Apparently a lot of 'come-ons' that she was angry about, but whatever," Osaka said. "I think this was her last Australian Open, so, okay, sorry she was mad about it."
However, during her subsequent press conference, Osaka apologized for her dismissive tone.
"I'm a little confused. I guess that emotions were very high for her," Osaka said. " I also want to apologize. I think the first couple of things that I said on the court were disrespectful. I don't like disrespecting people. That's not what I do."
Osaka went on to clarify that her vocal outbursts are self-motivating and not an attempt to rattle her opponent.
Cirstea, who recently announced that the 2026 season will be her last on the WTA Tour, later downplayed the incident. She called it a "five-second exchange between two players," insisting that "there was no drama."
Osaka, the No. 16 seed, will next face unseeded Australian Maddison Inglis in the third round on Friday.
