About 100 pupils and parents staged a protest outside a school in East Sussex against its introduction of gender-neutral uniforms.
Police attended the demonstration outside Priory school in Lewes against a new policy instructing all pupils to wear trousers.
Protesters holding signs reading "a new uniform for nine months is not sustainable" and "fast fashion is the second biggest contributor to climate change", argued girls should be allowed to wear skirts and that it was both wasteful and expensive to ask parents to buy new clothes.
A spokesman for Priory school said the uniform was designed to be practical and to encourage students to focus on their school work. "Our uniform also helps us to dilute the status placed on expensive clothes or labels and challenge the belief that we are defined by what we wear," they said.
"Instead, we encourage individual beliefs, ideas, passions and wellbeing and an ethos of camaraderie that is reflected in this shared experience."
Seems like an overreaction by the students/parents, but not sure why the school felt the need to refuse them entry or call the cops.
