The walls at Ermanno Scervino were lined with portraits of Marcello Mastroianni, John F. Kennedy, Marlon Brando and Steve McQueen, and on the runway, the mix of sartorial icons was reflected in a narrative of formal versus casual. Much of the story unfolded on the surface of things, in coated olive green fabrics or glossy black bombers in exotic skins, and Scervino turned his attention to denim to explore both smart and laid-back codes of dress, from sky blue denim suiting with lapels in contrast wash to waxed jeans, all set within the designer’s framework of clean shapes and modern classics.
