Unless I see a Che shirt or something I have literally no clue. There isn’t a Commie haircut or facial hair type that’s seen as communist here in the USA at least. Can’t speak for the rest of the world, or even for the rest of the US now that I think of it. When it comes to the MidWestern comrades idk tbh, I wear Commie Soccer Jerseys (mostly bc they look cool, partly bc they’re lefty) and a Deprogram hat sometimes but I doubt that everyone knows I’m a commie when I wear a Motörhead cutoff or my Jordan UCLA shirt. TL;DR You have no real way of knowing if someone is a Lib or an anarchist or anything just based on how they look, especially when capitalism sorta makes some people feel uncomfortable displaying their beliefs in public. I definitely think there are a decent amount of people who are too scared of the word “COMMUNISM” to call themselves Commies, but hold beliefs similar to us in many ways. And those people DEFINITELY aren’t dressing in commie clothes
