I just don't see that making sense. Maybe it's a generational thing, but I've never seen a person in a suit and thought they must have extra "pride" in their appearance. I mean, anyone can look decent in a (tailored) suit. It's easy. it's a standard corporate outfit because you don't have to think too hard about it. If anything I assume suit wearers don't have enough confidence to pull of a more individualistic look competently.
Meanwhile I see some of the pics from r/streetwear, and those folks have pride! Sweatpants and all, I can appreciate that there is an actual aesthetic there and that their outfits fit their body types and daily needs (especially for techwear).
Nothing makes comfort or lack of traditional formality unstylish in itself, other than biases and cultural gatekeeping at least. Dirty clothes are lazy of course, but so long as your clothes actually fit you and are clean + coordinated, its possible to have pride in your style and be comfy. Even if suit afficianados sneer, if you like it and others like it, you can be proud.
