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
