Here's the funny thing. The three piece suit was adopted by the politicians as an emulation of the dress code of "the common man". Since most men wore plain suits and plain shirts for everyday dress, in contrast with aristocracy which dressed in fancier, more elaborate ways.

It's ironic that it became the new dress code for the oligarchs and powerful oppressors. And now the common people dress even plainer and simpler. They're fighting over dressing in a symbol of modern political and financial oppression.
