Quote from : Tim Gunn's Fashion Bible: The Fascinating History of Everything in Your Closet Book

For men, the skirt was a 'sign of leisure and a symbol of dignity,' writes Quentin Bell. This is still true for men in high positions. After all, can you imagine the Pope, or Professor Dumbledore, wearing trousers? Have you ever seen a depiction of God wearing pants?
