Serena Williams on Saturday defended the president of the French Tennis Federation, who faced a backlash after saying he intended to ban outfits like the form-fitting catsuit Williams wore in this year’s French Open.

Williams said she spoke on Friday with the president, Bernard Giudicelli, who recently told France’s Tennis Magazine that he would introduce a dress code at Roland Garros because “one must respect the game and place.”

After several supporters in tennis and outside the game objected to Giudicelli’s decision as disrespectful to Williams, she told reporters that she was not concerned.

“The president of the French Federation, he’s been amazing,” Williams said at a United States Open news conference, adding, “We have a wonderful relationship.”
