France “Lift the Skirt Day”

In the city of Nantes, France, education chiefs have decided to make an interesting move in the war on sexism and gender inequality.
27 high schools throughout the area participated in a voluntary “Lift the Skirt” day, an anti-sexism demonstration where all students, guys and girls, were encouraged to wear skirts to school.
Arthur Moinet, one of the organizers of the demonstration, said the event was sparked by an ongoing problem with sexism in his region.
“We noticed that in a lot of high schools in our region, there are lots of cases of sexism and discrimination, so we thought we should do something to change that, and so we came up with the idea,” Moinet told Euronews.
What do you think? Is this demonstration another attempt to blur gender lines, or a new way to fight the war on sexism?
