This sounds too academic to me. Rather like the neat efficient market theory.
It assumes that people know what they are doing! :)   Immediate fail!

The efficient market doesn't work because of all the human illogical
emotional reactions, herd instinct, etc.
Similarly, fashion victims are trying to dress in the latest fashions,
not particularly to impress any group.
As you say, it also depends on fitting in to the environment you are
going to. People like to 'join in' and be one of the crowd.
(herd instinct, again).
