Billie Jean King famously beat Bobby Riggs in their $100,000 winner-take-all "Battle of the Sexes" tennis match, which took place September 20, 1973. King's designer for the match, legendary British tennis couturier Ted Tinling, brought along a shimmering dress that King looked great in, but she felt it was too scratchy. That's how the back-up option was introduced: this nylon dress that paid homage to the Virginia Slims Women's Tennis Tour. The morning of the match, Tingling searched high and low for rhinestones to stitch onto it, according to his memoir. "I would never have worn pink," Billie Jean King famously said of the historical moment.
