Person2: All the rage with whom ? I never see anyone wearing these designs on the street .
Person1: Did you know that fashion is cyclical ?
Person2: What , it keeps coming back ?
Person1: Precisely ! For example , Flares were popular for a while , then went out of fashion . Now we can start to see them coming back in again .
Person2: Flares ?
Person1: They're also known as bell-bottoms . They are a type of trousers .
Person2: It's too complicated . I'll just stick to the plain clothes .
Person1: That's fine , but then you'll always look plain .
