I would just think that taste has changed. I was actually thinking to myself that I prefer 2049's style as I was reading through this. But I was also born in the late 90's, so I assume it could be a generational difference.
Clothes in '80s were overall louder than the minimalist aesthetics of today. It all fits in with gen z's apprehension at being perceived, related to "cancel culture" and cameras everywhere.
It's not even so much that I like the taste / style of the fashion in the original Blade Runner, more that it just feels more real and interesting. The recent film feels like any other generic sci-fi movie.
