​After a round of press to promote her latest release The Bluff, Priyanka Chopra Jonas goes for a casual denim-on-denim airport look in a Nahmias set. The actor keeps the styling simple with a baseball cap and aviator sunglasses, letting the head-to-toe denim do the work. Matching jacket and jeans remove the guesswork, while a faded wash keeps the look relaxed enough for travel. The combination has become an off-duty staple, one that continues to resurface each season in slightly different forms.. Getty Images. Priyanka Chopra at JFK Airport. One of fashion’s most enduring pairings, denim-on-denim’s history traces to the 1950s, when singer and actor Bing Crosby was denied a room at a Vancouver hotel because, as the denim company’s historian Lynn Downey writes in Short History of Denim, “apparently denim-clad visitors were not considered high-class enough for this hotel.”.
