For her first match in the 2021 Australian Open, Serena Williams honored the late athlete Florence Griffith-Joyner, widely known as "Flo-Jo," by wearing an asymmetrical unitard—sportswear that the track and field legend popularized in the late '80s.

The Grand Slam champion's look, courtesy of Nike, featured black, red, and hot-pink color-blocks with one full-length leg sleeve.
