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.
I only have to wear them to fancy parties so I like them. Any work dress code that's not directly tied to health and safety concerns is a tool of oppression, of course. If you have to wear a suit to work that's bullshit.
Also, I'm annoyed by how suits are multiple layers up top and then usually thin pants. Feels like a missed opportunity for fancy pants. Also my legs get cold way easier than my torso does, who designed that.
