Last week, tennis star Coco Gauff warmed up for the 2026 US Open in a New Balance tracksuit featuring fall's mustard color trend. This week, on September 1, she returned to the sport's biggest stage in a different yet equally delicious, sunshine-inducing shade: butter yellow.
For her first official match of the tournament, Gauff defeated Turkey's Zeynep Sonmez in a navy tennis dress from New Balance. The sleeveless style from the Boston-based brand boasted some of the 22-year-old's favorite design features, including a scooped neckline, a domed cut-out along her lower back, and a ruffled skirt. Her headband and sweat wristbands came in the same shade of blue; from there, butter yellow sportswear took over.
