Like I know that, realistically speaking, they're not the worst results of imperialism and colonialism, but suits are just so boring, and their universality is representative of the results of imperialism in a clear and easy to see way. Like why did the evils of imperialism have to be accompanied by boring suits.
If I'd known so many people would comment I would have explained more. I don't mean that suits in and of themselves are boring. What makes them boring to me is their universality; they've become the default male 'formal' clothing in basically every country on Earth, due to imperialism. So if you were to take one male from every country, and tell them to dress formally, they'd all be wearing basically the same clothes. I think what would be interesting is different people wearing different clothes. Imagine how the UN would look, for example, if every delegate wore their culture's (not country, because many countries are composed of several nations) traditional/formal clothes, rather then basically everyone wearing a black/blue/grey/tan suit.
edit: plus on a less trivial level, there's probably something to say about colonialism of the mind when almost every culture starts identifying success/formality/wealth/power/etc with western clothing, rather than their own traditional clothing.
The Papua New Guinea delegate wore traditional dress once if I remember right
Indian politicians tend to wear Indian formal wear even while on international trips. I do agree it stands out in a crowd of suits
