Justin Bieber in Acne Denim Jacket

Wearing a double denim outfit, Justin Bieber was on hand to flip the switch on the Empire State Building. Justin's stint at the Empire State Building is to promote the new animated movie 'Arthur Christmas'. For the switch flipping event, Justin wore an Acne Denim Mechanic Jacket with a baggy pair of (too low on his backside) black jeans.
