If you're misquoted, contact the reporter, not the editor. But don't overreact, especially if the error is minor or not quite the choice of words you would have used. Take the time to look in the mirror. Straighen your hair, tie or scarf. You don't want viewers to be distracted by a crooked tie and miss hearing your words.

Avoid checkered shirts. Remember you are representing the university. Don't wear clothes with the insignia of another organization or university. Note whether the backdrop is appropriate. Talk with the reporter about the interview before its starts.
