On January 31, Najat Vallaud-Belkacem, France's minister of women's rights, made it officially impossible to arrest a woman for wearing trousers in the French capital.
The law required women to ask police for special permission to "dress as men" in Paris, or risk being taken into custody.
In 1892 and 1909 the rule was amended to allow women to wear trousers, "if the woman is holding a bicycle handlebar or the reins of a horse."
The law was kept in place until now, despite repeated attempts to repeal it, in part because officials said the unenforced rule was not a priority, and part of French "legal archaeology."
In July however, in a public request directed at Ms Vallaud-Belkacem, Alain Houpert, a senator and member of the conservative UMP party, said the "symbolic importance" of the law "could injure our modern sensibilities," and he asked the minister to repeal it.
