If you are asking whether or not you can chose to wear uniforms at a uniformed school than the answer is no. If you attend a uniformed school than you must wear a school uniform or you will be kicked out. If you go to a non uniformed school then you shouldn't wear uniforms either.
Many students fell that they shouldn't wear school uniforms due to the style of the uniforms. Students have a need to express their individual style and wearing uniforms can inhibit their individuality.
yes, school uniforms do help students. i myself am a student that goes to a school where you have to wear uniforms and it helps with the teasing and some of the drama. if you wear uniforms, you dont have to worry about a child being teased for their clothes.(:
