Three-time Roland Garros champion Williams caught the eye in May as she wore a black catsuit, which she said helped to protect against blood clots after the birth of her daughter.

But Giudicelli believes the American went "too far" and insists players must dress more conservatively to show respect to tennis and to Roland Garros in future tournaments.

"It's a bit late because the collections are already designed but we are going to nonetheless ask the manufacturers to let us know what is coming," he told Tennis Magazine.

"I believe we have sometimes gone too far. Serena's outfit this year, for example, would no longer be accepted. You have to respect the game and the place."
