So what? TFA is not about the working class nor does it need to be. Why this fixation on comparing yourselves with the poor?
Wigs, stockings and heels were associated with being of the aristocrat class. Which, as the article states, could make one wearing such things a target.
> During the French Revolution, wearing dress associated with the royalist Ancien Régime made the wearer a target for the Jacobins. Working-class men of the era, many of whom were Revolutionaries, came to be known as sans-culottes because they could not afford silk breeches and wore less expensive pantaloons instead
_Prior_ to the revolution, the Jacobins (who were largely bourgeoisie) would have been wearing that dress, distinguishing themselves from the working class (who _didn't_ wear the stockings). The revolutionary period is being used to illustrate a change here, not the norm.
