SERENA HAS WON her share of Grand Slams. Venus won them first, then helped pave the way to equal prize money for women at the Grand Slams, both Wimbledon and the French Open. Fashionable and fierce, these competitors, friends, sisters, and fighters were raised to be game changers on and off the court, Venus first, with her shadow, Serena, not far behind. Blow up convention: go to Fashion Week during U.S. Open week, say whaaat? Be friends with other women on the tour, wait, wait, then be real friends with each other—even when the little sister found her own self—no catfights, impossible! The lights shine bright no matter where Serena walks or whom she walks with these days, from the Royal Box to Queen Bey to Center Court in Queens, New York City. Her heart still belongs to her big sis and vice versa. “There’s your average loyalty,” Serena told The New York Times Magazine not too long ago, then there’s Venus loyalty, which “for lack of a better word is mind-boggling.” Deuce.
