Five years ago, David Smith wore an expensive suit to work every day.“I was a clothes addict（有瘾的人）”he jokes.“I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual（不经意的，随意的） clothes—khaki pants （裤子）and a sports shirt—to the office. He hardly ever wears a necktie.“I am working harder than ever.”David says,“and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday（but only on Friday）.This became known as“dress-down Friday”or“casual Friday”.“What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.”said business Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code.” “A lot of young people don’t want to dress up for work,” says the owner of a software company,“so it’s hard to hire people if you have a conservative（保守的）dress code.”Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale（心境，士气）. Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,”one person said. “For the same amount of money, you can buy a lot more casual clothes.”
