Naomi Osaka is making a significant impact at the US Open 2026, not only with her performance on the court but also through her bold fashion choices. The four-time Grand Slam winner, working with stylist Law Roach, has elevated her game-day attire, featuring custom designs for everything from practice arrivals to official matches.

For her second-round match, Osaka wore a striking all-white Thom Browne ensemble. The outfit, crafted from white silk gazar, included a pleated skirt and athletic mesh inserts, all detailed with embroidered tennis rackets. Underneath, she revealed a silver Nike two-piece set.

Earlier in the tournament, Osaka paid tribute to basketball legend Allen Iverson with a custom tulle and French-terry gown by Who Decides War. The dress was adorned with newspaper clippings of her career highlights, and Osaka accessorized with Iverson's signature red sweatband headband and matching armbands, completing the look with braided hair.

This homage to Iverson was inspired by Nike's season theme, which draws from basketball. A black Nike two-piece outfit she wore for a match featured a net-like embellishment on the skirt, further connecting to the basketball theme.

"He was an elite player on the court but also found a way to authentically merge culture, sports, and fashion," Osaka told Vogue, explaining her choice to honor Iverson. Her avant-garde style was also evident at the French Open earlier in the summer, where she showcased custom jackets layered over a gold sequined Nike tennis dress.

Osaka's fashion-forward approach extends even to her practice wear, which has included notable items like Supreme/Margiela x Timberland boots covered in dollar bills and sheer minidresses, highlighting her status as a significant figure in the fashion world.
