A group of boys at a Brazil school wore skirts after a transgender girl was disciplined and fined by teachers for wearing the "incorrect" uniform.
17-year-old Maria Muniz, who recently came out as transgender at Sao Cristovao de Colegio Pedro II, was disciplined by teachers and was given a fine after she wore a skirt to school instead of the boys' pants.
The school said that their Code of Ethics did not allow "male" students to wear female uniforms.
"I always turned up in trousers but I felt repressed and for me wearing a skirt was about expressing my freedom over who I am inside and not how society sees me," Muniz said.
But, when Muniz's classmates protested and wore skirts to support her, the school was forced to change their position.
The school said in a statement that it would change the rules to allow for greater gender expression, saying: "The current Student Code of Ethics will be overhauled with the participation of the whole community, including the active participation of students, who may suggest changes they deem necessary."
Muniz was elated with her fellow classmates' support.
"I am really happy about the way my classmates supported me, and I hope it serves as an example to others to feel encouraged to do the right thing," Muniz said.
