Nastri d'Argento 2016 - Why black suits again?

The Nastro d'Argento (Silver Ribbon) is an Italian film award - the oldest movie award in Europe. This year the awards ceremony was held at the Teatro Antico, Taormina, Sicily Island, Italy, on July 2, 2016. And what a surprise - all gentlemen were dressed in similar black suits, making them look one and the same.
