Its difficult to explain.
You got these guys, wannabe's. They want to be "it", but they never are. They aspire to be "it", but they arent. You see them and think, "meh, douchebag and/or just trying hard".
Then you get these people. Rare. They can do anything, and seemb genuine.
You can have 50 idiots wanting to be classy, they are perfectly suited and groomed, but its just not that. Then you have Pirlo, in semiformal trowsers and sweater, holding a glass of whine, and he is just "it". The genuine "it".
He can wear a plastic bag, and is still class. He can wear that bag, and he'll still be more class then anyone in a suit
You have 80 years of excellent actors, and then there was James Dean.
