"You have to behave in the way that people behave in the country that accepted you, and that is it," Cogolin Mayor Marc Etienne Lansade told CNN.
"If you are accepted in Rome -- do like Romans do," he said, adding, "go in Saudi Arabia and be naked and see what will happen to you."
Lansade, of the right-wing National Front political party, is maintaining the ban despite a ruling by France's highest administrative court that mayors do not have the right to outlaw burkinis.
