A male student who has worn women's clothes to school all year was turned away from his high school prom because he was wearing a dress.

Kevin Logan, 18, went to the West Side High School prom on Friday in a slinky fuchsia gown and heels. He believes officials discriminated against him by not allowing him inside.

"I have no formal pictures, no memories, nothing. You only have one prom," he said.

Logan, who is gay, received an $85 refund for his prom ticket Tuesday but was not satisfied. He said he is considering filing a complaint with the Indiana Civil Liberties Union.

Sylvester Rowan, assistant to Gary Schools Superintendent Mary Steele, said school policy bans males from wearing dresses. Excluding Logan from prom was based on "the dress code, not the student's homosexuality. That's his personal preference."

Tyrone Hanley, the youth program coordinator for the Gender Public Advocacy Coalition in Washington, D.C., said he often sees cases like this and called it gender-based discrimination.

"Prohibiting really short skirts for everyone is a fair dress code; prohibiting them for males is not," he said.

Logan said he had spent years defining and exploring his sexuality. This year, he took a major step by dressing as a female every day, wearing makeup, a hair weave, nails and girls' fitted jeans to school.

His mother, Donnetta Logan, said she was not surprised by what she called the ignorance of school administrators.

"I tell Kevin that in society there will be those who accept him and those who won't."
