It's the camera that makes this outfit. It's so touristy and geeky it's cool, particularly because it is an old-fashioned shape. The vintage look of the camera goes well with the leather jacket which looks old and the fine, grey scarf around Hans' neck. The blonde beard also echoes the shearling on the collar of the coat which makes him look even blonder.
