Serena Williams knew all eyes would be on her at the US Open this week — it’s extensively expected to be her closing event, pursuing her new announcement that she would be “evolving away” from tennis. The sports star chose to mark the celebration with a stunning black tennis gown worn on Monday at Arthur Ashe Stadium in New York, when she gained her very first spherical match towards Danka Kovinić. She also wore the outfit when she defeated planet No. 2 Anett Kontaveit in their singles match on Wednesday, advancing to the 3rd round.
