Compare that to the hyper-maximalist 80s movie outfits. The original Blade Runner has more creativity in one outfit than pretty much the entirety of the sequel.
I wonder why that is. My guess is that it's just a symptom of the same thing that causes everyone to stop buying colorful cars, and instead default to a grayscale one: fear that being too outlandish or creative will turn off potential customers/viewers.
It went into to much detail, the film has its detractors, but the book itself was fascinating. Although I still buy books I don't think I spend enough time reading them.
