How can the quote below prove that school dress codes are harmful?

Question

A research analysis of 29 public and charter school dress codes show that 59% of high schools regulated the length of skirts and shorts and 55% regulated tightness and fit of clothing.

Answer 1

This quote alone does not speak to the harm of school dress codes; however, in combination with other pieces of evidence, you could explore different avenues of harm. Maybe the types of clothing being regulated might speak to the gender of students who face disproportionate amounts of punishment on top of the gender discrimination they already face. Perhaps you could look at academic outcomes across time to see if higher or lower percentages of schools enforcing a dress code affect those outcomes.
