Acclaimed writer Roxanne Gay added her voice to the debate, posting: "What incentive would Serena Williams, GOAT, have at this point in her career to play the French Open when the tournament is being blatantly disrespectful to her?"
"Everything's fine, guys", Williams said on Saturday morning at the US Open, explaining that she had already resolved the issue in a conversation with French Tennis Federation president Bernard Giudicelli.
The 25-year-old also seemed annoyed at some less-savvy iPhone users, who were taking too long with their cameras.
"Not necessarily a new place", she said, "but definitely an upgraded one". My whole team is basically French, so we have a wonderful relationship. "I think sometimes we've gone too far".
The 23-time Grand Slam champion made her return to Grand Slam tennis following the birth of her first child previous year and wore the eye-catching outfit, inspired from the Marvel Comics film, at Roland Garros.
When asked about her powerful look during the tennis tournament, she told reporters it made her feel "like a warrior princess" from the blockbuster Marvel Comics film "Black Panther".
The backlash continued into Saturday, with Hall of Famer Billie Jean King weighing in on Twitter.
"I wear tights that keep everything going with my blood", Williams said.
Aside from making her feel like a warrior and giving a nod to the biggest superhero movie of all time, she also wore her catsuit for health reasons. Williams was probably just following protocol.
"I'm always living in a fantasy world", she said. "It's just new and it's fresh".
The third seed admitted she was "a little bit nervous" for her opener on the brand new $AU200 million Louis Armstrong Stadium court, a 12,000-seat stadium with a retractable roof next door to the massive Arthur Ashe Stadium. I thought after having a child I would be more relaxed, but I'm not. I feel like I take it just as serious if not more.
That match was played in the new Louis Armstrong Stadium, with obstacles she didn't face past year when her final few matches were in Arthur Ashe Stadium. I work just as hard, if not harder, actually.
