A federal judge in Mississippi denied a transgender teen’s emergency request to be allowed to wear a dress and heels to her high school graduation. As a result, the student missed her graduation ceremony this weekend rather than be “humiliated,” she said.

Last Thursday, the American Civil Liberties Union (ACLU) and the ACLU of Mississippi filed a lawsuit on behalf of the 17-year-old student, identified as “L.B.,” and her parents against Harrison County School District.

According to the lawsuit, L.B. “entered high school as a girl and has lived every aspect of her high school career as a girl.” CNN reports that classmates, teachers, and administrators at Harrison Central High School have been aware of her gender identity for the past four years, and she attended prom wearing a blue dress without any objection from the school.
