Why this underwear campaign is the most important thing you'll see today.

International Women’s Day is here. And these women have a message for you – on their undies.

A third of the world’s women have been subject to physical or sexual violence. Realistically, that number is probably higher, given the reluctance of women to report these crimes.

AleXsandro Palombo, a contemporary artist and activist, is known for his subversive art pieces including depicting Disney princesses with disabilities and as survivors of domestic violence.

This year, Palombo has launched a social campaign highlighting the unacceptable rates of violence against women, by enouraging women to express themselves on their underwear.

These women have written as a powerful protest against machismo and brutality.

They are writing for themselves, and others just like them, all across the world.
