Wearing the right clothes is an essential element of good leadership, according to psychologists in the journal Scientific American Mind.

The psychologists argue that successful leaders are chameleons who shape themselves around those they want to influence. They say that being perceived as “one of us” makes it easier for them to get their own way.

One of the psychologists, professor Alex Haslam from the University of Exeter, said: “Leaders try to transform themselves so that their personal biography and even their appearance come to be symbolic of the group as a whole.”
