In the United States, a fashion revolution is going on. In offices, people are beginning to dress more casually on Fridays. They wear blue jeans, T-shirts and sandals instead of dress clothes such as suits.
Office workers says that casual clothes are very comfortable and make people feel friendly.
It makes them work harder. This new dress code is especially popular in California. Many workers are very happy about this, but some people don't like it, because they like to dress up. They say it doesn't feel right. Also, they say in the case of formal meetings they can't wear casual clothes.
