Why does Brady insinuate that Drummonds suspenders come from the great metropolitan?

Brady insinuates that Drummond's suspenders come from the "great metropolitan" to mock him and highlight a perceived disconnect between Drummond's rural identity and urban sophistication. This jab serves to emphasize Drummond's status as an intellectual outsider in a largely agrarian community, suggesting that his beliefs and attire are influenced by urban elitism rather than genuine local values. Ultimately, it reflects Brady's attempt to undermine Drummond's credibility and appeal to the local audience's sense of pride in their simpler, more traditional lifestyle.
