In a season where the coat is king, Yamamoto served up a volley of period showstoppers in a lengthy ode to his house’s DNA. Among the main characters was a folksy fellow swathed in blanket coats or in morning coats — a house icon — in rugged fabrics. These came over cropped suits in coarse checked and pinstripe wools, or fluttering rust silk pajamas. In the formal military segment, a double-lapel blue coat was among the standouts, while a long black coat with a hood flowing from the collar took on ethereal airs. A group of real life models of considerable age and portliness breathed life into certain looks, conveying the message that elegance is just as much about attitude as it is style.
