Cultural fads, like Americans wearing leg warmers in the 1980s or flannel shirts in the 1990s, are often followed because people want to fit in and go along with the crowd. This type of conformity is known as influence.

normative

Explanation:

We can say that Normative influence is clearly a form of influence whereby an individual conforms or tries to act or even goes ahead to act like the majority in order to gain approval and acceptance.

This simply implies letting go of oneself and taken up the popular opinion of the majority in order to be accepted or gain approval by the majority.

This was what led to Cultural fads, like Americans wearing leg warmers in the 1980s or flannel shirts in the 1990s.
