Students at the Blue Coat school in Oldham veered sharply off their strict uniform policy this week.
School Reporters' cameras were rolling on the story of Purple Day, when students were allowed to wear purple tights, hair bands, ties and hair clips in a bid to raise funds and awareness for the Lavender Trust.
The Lavender Trust is a charity that aims to support younger women diagnosed with breast cancer.
Student reporter Mary, a Year 9 student, said the idea for the funding drive and the story stemmed from Heather McNeill, one of the school's heads of house.
"Miss McNeill told us that when she had breast cancer she felt very well supported, but she worried about how younger women in her situation would feel," Mary said of the story.
She said that, as a television story, Purple Day offers students a personal connection with their school and the benefits of the charity.
"You feel more like you're making a difference when you know the person like Miss McNeill."
Teacher Claire Bayley said the students' enthusiasm for both the charity and the subsequent story was widespread.
"We're having a great day and we've had lots of students take part from other years," she said.
Miss Bayley said the awareness of the charity was raised across the community because of the sight of Blue Coat girls sporting purple.
