The origin of the Tennis Bracelet

Tennis player Chris Evert made it her style signature to trade out tri-striped sweatbands for delicate strings of diamonds on her wrist, catching the light of the sun when she played on the courts.

When her bracelet went flying off her arm at the US Open 1978 and the match was halted to find it, everyone started referring to it as the “tennis bracelet.”
