Of or relating to the upper or middle classes. This term is not generally used by people in the American middle class, and using it may cause the speaker to be identified with the working class. When it's used, it often describes something that is "middle class" or "upper class", with positive connotations.
From Elvis Presley's Hound Dog: "She said she was high class; well, that was just a lie."
