休闲星期五是指那些平素对着装需要严格的公司，在星期五这一天允许职员穿着不同程度的休闲装。这一着装趋势的时尚缘于大家厌倦了工业年代的统1、标准的生活方法和着装方法，当然，也遭到了成衣制造商的影响。在某种意义上，也可以说经济决定所有。
Casual Friday began in the late 1950s originally as an attempt to raise worker morale1 in the new white-collar office environment. At that point only a few companies encouraged it, and it was not widely popular. In the late 1970s, when the production of cheap clothing outside the United States became more widespread, there was a massive campaign by large clothing producers to make Casual Friday a weekly event. It was the hope of these companies that they could undermine the formal clothing industries in Europe and create more of a market for their goods produced in cheap Third World factories.
Casual Friday along with dressing2 casually3 during the week became very prevalent during the Dot Com hey-day of the late 1990s/early 2000s. During the hey-day, some companies were so relaxed that shorts and sandals were permitted. After the bursting of the Dot-Com bubble, there was a backlash by many companies with the reinstatement of dress codes.
Nowadays, Casual Friday has become a business custom which has spread all over the world, wherein some offices celebrate a 百度竞价推广i-reprieve from the constrictions of a formal dress code.
Whereas, during the rest of the week, business shirts, suits, ties and dress shoes are the norm, on Casual Friday workers are allowed to wear more casual dress. Some companies allow jeans, T-shirts, and sneakers but others require smart casual dress.
