Earlier this summer, Coco Gauff's custom New Balance x Miu Miu outfits complied with Wimbledon's strict dress code. But once she arrived in New York City for the 2026 US Open—where she regularly competes in much more statement-making shades—she couldn't wait to wear anything but all-white.
Gauff's first style grand slam of the week wasn't anywhere near the USTA Billie Jean King National Tennis Center. On August 25, while filming a commercial for New Balance in Manhattan, Gauff served a tracksuit-inspired take on fall's mustard yellow trend.
