Last week, Coco Gauff appeared in a new fashion ad for Miu Miu - but instead of focusing on the look itself, many fixated on the tennis star's hair. Robert Prange / Getty Images In the ad, Coco posed on a tennis court wearing a red polo shirt, a navy blue miniskirt, and black loafers, styled with a brown leather bag. Her hair - worn in its natural 4C texture - was parted down the middle and pulled into a bun with a blue hair tie.
