I feel like maybe around 2012 the whole concept of eras died.
Like I can clearly visualize items/people/media from the 60s/70s/80s/90s/00’s, but everything is homogenized now and there’s really no “style of the time” either. I think everything from 2013+ will just be remembered as a malaise era, if anything. Maybe the style of the 2050’s will be post cyberpunk apocalyptic? I have no idea.
2000s was very emo-/scene-heavy. Lots of bracelets and mixing of black and neon.
2010s are the best argument for you, probably. It was more of a blend of things 🤷♂️ hipsters and preppy looks got pretty big, but nowhere near as homogenous
2020s will be COVID themed with broccoli hair
All that can be said has been said. All that can be done has been done. Nothing is new under the Sun.
