Business casual

Business casual is a popular dress code that emerged in white-collar workplaces in Western countries in the 1970s in response to the power disaster of that decade. Government permission to raise thermostat settings in office buildings led managers to approve employees to give out with ties and jackets that had been part of predictable business clothes. Many information technology businesses in Silicon Valley were early adopters of this style of dress. It has partially supplanted business casual wear suits and neckties, sometimes called global standard business clothes, which were previously the regular clothes for managers and professionals. Trousers complete the package; jeans are rarely acceptable in workplaces as part of business casual clothes, but some Silicon Valley entrepreneurs such as Steve Jobs are known to wear jeans as part of the business casual look.
