Denim Day is a campaign to raise awareness and educate the public about rape and sexual assault. This movement arose from the outrage that followed an Italian Supreme Court decision in 1998 to overturn a rape conviction because the victim wore tight jeans.
We celebrate Denim Day in honor of a woman who was forcibly raped by her driving instructor. The woman pressed charges, but the case was dismissed because the judge decided that,
…because the victim wore very, very tight jeans, she had to help him remove them, and by removing the jeans, it was no longer rape, but consensual sex.
