So, in the Fallout universe, the world never culturally developed past the 50's or 60's. That's why Fallout has it's retro-futuristic aesthetic. However: is it reasonable to assume that the pre-war culture was not a direct continuation of the 50's? If you begin to consider to the timescale of Fallout, then the idea that American culture and fashion stayed (mostly) the same is... absurd. From the splitting of the timeline in 1940-something to the war there's nearly a 120-year time difference. I mean, that's as if it were popular to wear tricorn hats and leggings in the 1900's. Can we assume that the art-deco aesthetic and style that was popular in America before the war (War?) was a culture revival? Can we also assume that American culture in the Fallout universe might have followed other trends?
