Freedom of Speech

When you are kicked out of homecoming because your dress is "too short" or "too provocative." Does that violated our freedom of speech. What happens when the the same dress is aloud in by other girls? What happens when our First Amendment is violated ? Do we have the right to protest or will they call the police on us? Is there any way for us to stand up when our rights are violated and not get into trouble? Though when it comes to Dress codes in the schools their is a lot  consaveral about what is aloud is not. If you're under the age of 18, you don't have as many rights as you think. What does that tell all the minors in the world? that they are not as free as us over 18?a school administrator can restrict a student's speech or expression if he or she feels it is disruptive to the educational objectives or discipline. So when it all boils down to is that those in high schoolkids nothing really to say when it comes to dress codes because that have less rights.But as i was saying before they school had let the same dress in for different girls. What does that tell you?
