Normal people by reading magazine or watching television, try to imitate famous personalities. These people do this to follow fashion and they feel pleasure to be look alike their favorite people. I believe that it is not fine to fake one appearance, as everyone have its own personality.
In recent times, it is easy to replicate anyone, especially to stars, as different means of sources are available. People imitate famous personalities because they are their fans. They want to be look similar like them and they feel happy when they wear the same outfits or get the same hair-cut done as their eminent stars do. Furthermore, popular personalities follow the latest trend of fashion: therefore, it is easy for ordinary people to follow the actor or actress by watching them in fashion shows, dramas or serials. This is how people get in touch with the recent fashion and following these make them different among individuals.
I do not agree that to copy someone is good, one should have separate identity. People ought not to be identified as the fan of other, for the reason they lose their identity. To elaborate, individuals who are obese, if they try an outfit which is tighter to them: then the suit will not look appealing on them. Likewise, blonde hair color is not for every complexion, women change their natural hair color, just to follow fashion, but if this color do not go with their complexion, then they feel awkward in the gathering. So, it is better to follow those things which enhances your personality.
In conclusion, people go after celebrities to duplicate them and to be updated about fashion industry. It is not appropriate to put oneself in same shoes as big names, in this way individuals loose themselves and their personality.
