But while she opted for another dramatic on-court ensemble before facing Katerina Siniakova at Arthur Ashe Stadium, her mom caught the eye after making a fashion statement of her own in a smart suit. Osaka stepped out in an all-white outfit, including a long overshirt featuring tennis rackets stitched into the design.The long tail flowed behind her as she walked onto the court, tripping on the fabric beneath her feet as she walked to the net for the coin toss and to shake hands with her opponent. The white for the day-time session was a complete contrast to Monday’s all-black skirt and tank top promo in the night session on Arthur Ashe, and also a complete contrast to her mom, Tamaki, who was pictured watching on dressed very smartly in the stands. Once the match started, Osaka wasted no time asserting her dominance and taking the first set 6-2. She lost the second set 5-7 but bounced back to take the decider 6-1 and safely progress to the third round.

She wore arm sleeves and a headband as she walked onto center court in a wide, floor-length skirt and sleeveless hoodie, discussing her Nike outfit after the win. ‘It’s my, I guess, my tribute to Iverson. I really like him a lot,’ Osaka said after the win. ‘I mean, Nike said basketball, so I said, ‘OK, you want basketball, I’ll give you basketball.” Earlier in the week, she called Iverson a ‘trailblazer’ in a press conference while wearing a t-shirt featuring an old issue of SLAM magazine with him on the cover. Osaka added: ‘I think he’s also someone that I look up to a lot, because he’s done a lot in fashion. Whether it’s on purpose or not, he’s shifted the way that NBA players dress. ‘I also think the whole conversation around clothes in sports, and also just expressing yourself through style, I feel like he’s someone that I look up to in that regard.’ Osaka said she has never met the basketball Hall of Famer, but said ‘hopefully he’ll see this,’ suggesting a future meeting could be arranged. Iverson is now interested in making that happen, writing on Instagram: ‘Wow, what a honor!! BIG FAN can’t wait to meet you.’Osaka wore a dramatic veil outfit compared to a jellyfish at the Australian Open earlier this year, then became the subject of debate among opponents at the French Open in June.After arriving for her first-round match at Roland Garros in a flowing black skirt and corset, then unveiling a shimmering gold dress, her opponent Laura Siegemund aimed a pointed comment in her direction.

That’s totally fine with me.’ But Donna Vekic, who Osaka faced in the second-round, told critics to ‘relax’ and embrace Osaka’s approach. ‘Some people take tennis way too seriously,’ she said. ‘Relax, it’s just an outfit. I think it’s good that she’s doing different things, expressing herself through fashion. ‘Whether it’s good or bad, that’s a different thing, it’s fashion.’ And Osaka certainly shows no signs of dialing back her creative fashion choices, continuing to make the most of the platform the US Open provides to express herself.
