Jane Avril, as depicted by Toulouse-Lautrec, secretly wishing she was wearing jeans.
When the law was enforced in 1800 it was designed to limit the number of professions that a woman could take on, but it became more and more outdated as bikes soon proved popular and then women had to take on men's jobs during World War I. However, without it being officially overturned, there was theoretically nothing stopping a police officer from arresting and detaining a woman just for wearing trousers - until today.
Strangely enough, it was a conservative politician from France's UMP party who applied for the law to be revoked; it was then championed today by the Minister for Women's Rights, Najat Vallaud-Belkacem. She pointed out that the old-fashioned law didn't fit with the constitution and equal rights principles, so it was thankfully ditched in favour of common sense.
