Tuesday is the Center for Women and Families' second-annual denim-day.Thousands of people in the area are wearing denim to work to raise awareness of sexual assault.Center for Women and Families' President Denise Vazquez Troutman says the threat of assault exists everywhere."One in six women will be the victim of sexual assault," she says. "Also, two college campuses [in Louisville], huge prevalence there – we are a huge college community. So if the statistics are one and six, just think of our own community."The significance of wearing denim comes from an Italian rape trial, where a judge ruled that a victim's blue jeans could have only been removed by the victim. To protest the decision, California legislators wore denim and the idea spread to other cities.
