In Illinois, however, a federal judge last year dismissed a lawsuit against the City of Chicago filed after police charged a topless protester with indecent exposure. The woman was participating in a "GoTopless Day" event organized by a nonprofit organization that advocates for the right of women to appear bare-chested in public, and said the city's policy violated her freedom of expression guaranteed by the First Amendment. In dismissing the case, the judge noted that the Supreme Court has held that "public nudity is not inherently expressive."
