Denim Day stems from a story about an Italian judge who overturned a rape conviction because he said the victim had been wearing tight jeans, and the suspect couldn't have gotten them off without her help.
So people in Wisconsin communities are wearing jeans today to support that woman, and all other sexual assault victims.
A Women's Community sexual assault specialist, Jessica Lind, says sexual assault is the most under-reported crime, often because the victim knows the attacker. That's why it can be a difficult crime to work through and talk about. But she says silence is what makes sexual assaults a frequent crime.
Students at UW-Marathon County are raising awareness of sexual assault, by collecting jeans. They'll be using art to remind their peers about the prevalence of violence in our communities.
"We're hoping to just decorate them, put them up let people know what's going on," says Rachel Samuelson, from the Student Government Association.
Lind says young people need to learn more about the crime, because it can happen to one in six women on a college campus.
"It's typically people that we know that we trust and it can really be a diff crime to work through," Lind says.
This is the first year Wisconsin is participating in Denim Day.
