We often see people in different offices wear different clothes. In America, a businessman goes to work in a dark suit, with black shoes, socks and a tie. A reporter goes to work in old blue jeans, a work shirt and sneakers(运动鞋). These two kinds of clothes are suitable for their work.
If you are a college student who will leave school soon, before starting a job, you have to buy some new clothes. And you'd better have a look at “what everyone else is wearing” in the office. On certain(某种) kinds of business occasions men wear only suits with white shirts and dark ties. On others, men can wear jackets.
Dressing is very important. Without it, there is no successful fashion. It would be helpful if everyone looks at himself in the mirror before leaving home every morning.
