The Athletic has live coverage of Day 4 of the 2026 French OpenPARIS — No one turns the tennis court into a catwalk quite like Naomi Osaka.At the French Open Tuesday, the four-time Grand Slam champion staged an outfit reveal once again, striding out for her first-round match against Germany’s Laura Siegemund wearing a black corset and matching pleated, cascading skirt that skimmed over the clay. They were layered over a gold dress designed by Nike, striped with sequins which shimmered and sparkled in the Paris sunshine.Osaka’s tennis shone, too, in a 6-3, 7-6(3) win that felt straightforward considering Siegemund’s ability to knock opponents off rhythm with her awkward, slice-laden game and use of tennis’ dark arts.Osaka faced 2024 Paris Olympics silver medalist Donna Vekić in the second round — and gave fans another look at the outfit, this time with a slightly oversized golden jacket in the same style as her dress, and a cream version of the cascading skirt that popped against the red of the clay.For Osaka, blending high fashion into her day job is both a crucial form of self-expression and homage to her predecessors such as Venus and Serena Williams, who caused a stir and defined an era of tennis fashion with their boundary pushing designs.She collaborates with couturiers on the kits directly and has her own creative team. She’s so engaged in the world of fashion these days that she even took a quick trip across the Atlantic to attend the Met Gala in New York, between the Madrid and Italian Opens.“I feel like fashion, for me, I tell people, I don’t talk a lot, so that way I can talk through my clothes. That means I can be as loud with colors or patterns or fabric as I want,” Osaka said in a news conference at the French Open.“That’s the fun part, you know. I feel like we lost that a little in tennis. I always tell people I grew up with Serena’s and Venus’ grand reveals. I literally can look at a picture and probably tell you what year that outfit came from.
