Snow clothes or no clothes (almost) - why?

There have been photographs in the news of clubbers walking through the icy conditions wearing no shoes (or thin, strappy sandals), and what I consider to be 'scraps' of clothing during a night out. As someone who was very poor as a child and often without adequate warm clothing I struggle to understand why anyone would choose to go out into the freezing cold barely dressed.
I cannot imagine how worried I would be as a parent if I saw a child of mine going out so inadequately dressed for the weather. Do they not actually feel the cold? Why do they do it?
