In 1992, an 18 year old girl was raped by a 45 year old. He was arrested and convicted but later appealed the result. The Italian supreme court ruled that her jeans were so tight that she would have needed to help the perpertrator remove them, and by removing the jeans it was no longer rape but consensual sex. They called this the “jeans alibi”. Denim day is an annual awareness event, protesting the result and promoting #SAAM every year.
