Dress code may be good for some schools *cough cough, cathlics, couch*, oh excuse me =)
But I think that dress code in most schools is a very bad idea. Some kids express themselves by what they wear. Plus, it makes it MUCH harder to tell kids apart if like say, one pulls the fire alarm then runs into a crowd of kids (man, thats not a bad idea about getting away with stuff

).
So, in conclusion. Whom ever though about dress code should be poked in the eye with a hot metal spike by a midget (no offence to any midgets out there).
