She’s long been known for her love of fashion and pushing the boundaries of court style.However, we doubt Serena Williams’s latest look of tennis champ-meets-geek chic will catch on.The World’s Oldest Female No.1 showed she wasn’t afraid to laugh at herself as she dressed in a wacky ensemble in Miami on Monday.The 31-year-old, who is in Miami for the Open, wore a purple tennis top and skirt with a sunhat and geeky glasses covered in tape as she shot the new Wilson Tennis campaign in Coral Gables.She tweeted: ‘Guess who at a #wilsontennis shoot.’It appears Russian tennis player Victoria Azarenka, who won the Australian Open Women’s Singles this year, was nearby and was overhearing Serena during the shoot.
