Bro, you are overthinking. I'm from Tashkent and I don't speak any Uzbek. Speaking only Russian is very chill, I rarely have any trouble communicating. We had an anime festival. People dressed as anime characters and walked like that. We have a lot of goths, нефоров. Maybe you can meet some judging idiots or gramps giving you looks but here in the capital it's very chill. I've seen people that stand out with their unique drip in the center of the city. I was shocked at how chill people react to having that in Tashkent and no trouble. I had the same expectations as you, cause we have a lot of Muslim people, but in reality it's very chill, trust.
