Male students at a secondary school in Co Carlow are planning to wear leggings to school, to protest an apparent rule that female students should not wear tight-fitting clothing to PE.
Female students at Presentation College Carlow were asked not to wear leggings or tight bottoms.
One parent feels the school is bodyshaming her daughters, and wants them to aplogise.
She said: "I'd like to see the school offer now an apology and retract what they said to the female students.
"If they wanted to enforce the dress code, they should have spoken to all students: male and female".
An online petition against the policy has been signed by some 3,500 people.
Students also put up notices in the school on Monday, in protest at the move.
One male student wore leggings to school, with plans for more students to do so on Friday.
Meanwhile the school has issued a statement, suggesting its uniform policy has not changed.
It said: "The rules concerning the correct wearing of our school uniform have not changed since previous years, other than the introduction of a half-zip top for first year students this year.
"Students are regularly reminded of school rules and regulations at assembly."
