What's wrong with a graphic tee? They're cute and colorful, and you can match several of them with your shoes when you start to run out of clothes. Individuality is important and something that should be encouraged!! Let people express themselves and stop trying to make everyone look the same!!
Graphic tees are a form of expressing yourself through patterns or words.
Sometimes students like to wear inappropriate words on their shirts, so that is the case where someone may argue YES.
But, you would not be able to express your personal style without graphic tees.
So they shouldn't be banned
