Cyberpunks became well dressed because manufacturers realized it was a way to sell people things, probably around the time The Matrix came out. If the aesthetic is old, grungy clothes, there isn't much money to be made.

But if popular media shows cyberpunk aesthetic as chic and cool, now we can sell shiny pants to 20 year olds.

Maybe I'm just extra disillusioned today, but it does seem like mainstream marketing and sales is the death of all things. Now I am become salesman, destroyer of worlds.
