Fashion is a term commonly used to describe a style of clothing worn by most people of a country. A fashion usually keeps popular for 1-3 years and then is replaced by another fashion. Even though there are a lot of changes in fashion, most people do not easily hope for the changes.

Nowadays more and more young people prefer following the fashion. On this phenomenon(现象), different people have different opinions. It is held that one should follow the fashion so as not to be looked down or seem strange. But it is also held that one should have his or her own judgement(判断).

Those who hold the first opinion think that society is progessing and one should get used to the changes. In their opinions, if everyone always follows the old fashion, there won’t be any change and naturally there won’t be much progress. However, those who hold the second view think that one shouldn’t follow the fashion without having his or her own judgement and characters.

As for me, I agree with the second opinion. Of course, it’s good for people to keep up with the fashion, but this is not to say that people should follow the fashion blindly(盲目地). If all the people follow the same fashion, there will be no variety and the whole society will be boring.
