Young people today have as many self imposed rules as my grandmother used to have. Rules about being cool. Rules about gatekeeping. They would 100% be calling people out for wearing white during the wrong season back in the day, only they'd call it clowning on them as if it's any different.
These are things that go in cycles. When people have been doing things in a bunch of subcultures it becomes "ugh, why are you trying so hard to be different" and when people have being all doing the same thing for a long time it's "ugh, why are you trying so hard to fit in". You hit a peak then everybody gets disillusioned and starts doing something different. It's cool to be ahead of the trend.
