Jonathan Escobar said his outfits -- including skinny jeans, wigs, vintage clothing and makeup -- express who he is, The Atlanta Journal-Constitution reported Wednesday.
"I don't consider myself a cross-dresser," he said. "This is just who I am."
He said the assistant principal at North Cobb High School gave him the choice of dressing in a more manly fashion or being home schooled. The official said Escobar's choice of dress caused a fight.
The school has a dress code and leaves up to administrators the final decision about whether clothes are disruptive.
Escobar, 16, moved to Cobb County from Miami to live with an older sister. His high school in Florida didn't have a problem with the way he dressed, but his parents did.
His sister, Veronica Escobar, said she urged her parents to let Jonathan live with her. She said she is shocked by the school's reaction.
