When even the bankers and accountants are dressing down, you know that casual dress is here to stay as a workplace norm. JP Morgan and PricewaterhouseCoopers are the latest to hang up their suits. While business casual is hardly news in most circles, having such traditional, buttoned-up industries jump on the casual train represents a true sea change.
