CHASING CHIC: What’s the suitable attire for a high-stakes chase that involves jumping over rooftops, flying on top of car hoods and climbing up chimneys? For Tom Cruise, the sartorial choice would be Giorgio Armani. In his newest action flick “Knight and Day,” his secret-agent character Roy Miller sports a navy pin-striped Giorgio Armani made-to-measure suit on the run in Salzburg, Austria. Armani’s creation proves to be quite durable. It remains chic through the end of the scene, when Cruise’s secret-agent character plunges into a freezing river.
