I am definitly a advocate for school uniforms in all publics schools I found a good article
http://www.educationbug.org/a/public-school-uniform-debate.html here giving some good pros and cons just a few examplesa are :
Wearing a school uniform will prevent cliques or groups
Stealing Items and belongings would be less likely if everyone is wearing the same thing.
Wearing a school uniform can help Identify intruder’s on campus quicker than when students are all in street clothes, intruders will less likely blend in.


Uniforms will leave students feeling less unique or leaving student feeling unable to express themselves through the way they dress.
Uniforms can be costly and create hardships on families financially
Uniforms can be unflattering for different body shapes and sizes and can hurt a student’s self esteem
