Dress is used to express ones self and to cover ones self. Some people really care about their clothes; others do not. To judge someone on the way they dress is the epitome of shallow behavior. You are basically taking your own ideas, morals, misconceptions and prejudices and placing them on someone else. Since when are you the moral authority on what is "proper" and what isn't when it comes to clothes? What if you are wrong? Yes, it is very wrong.
