Should Teachers have a dresscode?

Should Teachers have a dresscode? My personal opinion, no, I don't think so. Because they are proffesionals of course. And they all want us to follow the dresscode rules too. Because, if we don't, it would be chaos.There would be alot of bad doings. One, students' grades would go lower because they would all keep looking at other peoples' clothes. ESPECIALLY THE GIRLS!!! Two, if there was no dresscode, students would wear anything they want with out a care. And clothes that have gang-related pictures and drugs, can lead to students doing that stuff. Talking back to teachers, ex. So, thats why teacher gave us one. But Teachers don't need one themselves. Because they are Teachers! highly trained proffessionals! This article would give you more reason why.
      And besides, why would teachers have a dresscode anyway? Seriously, it won't change what they wear anyway. Teachers don't wear Short-skirts, or Angry birds shirts, that ryhmes. They wear a shirt, tie, or, Shirt and buisness skirt. Like every teacher should. And pants. And they want us to follow that so we can be more proper, respect your peers more, because, sometimes your clothes are based on you. That's why people talk bad about you. It's not true though. If we all where the proper clothes, like the teachers, we would have more respect. And teachers have lots of  Respect from us. So, why should teachers have a dresscode? It doesn't matter.
