Is it a side effect of internet? Easier to engage in highbrow activities from anywhere and combine it with a family life. Another contributing factor is the presumably larger percentage of women in the elite.
Interestingly enough, official replicas of this jacket were recently made and sold for $400. They sold out instantly. This is because people want to associate themselves with the "aristocracy" of Princess Di. She isn't quite "ordinary" yet. :) https://www.mitchellandness.com/team-varsity-jacket-philadel...
You can't decouple Princess Di from the kelly green or from retro 90s pop culture, whether you're a hipster who first saw the picture at Middle Child Clubhouse & just liked the vibes or if you were just paying attention to the news at the time. Any time you see the Philly media (social, traditional, even sports talk radio) talk about kelly green, they bring up Diana. It's as reflexive as the Philly Special, pickle juice, 4 & 26, etc. Scroll your socials back to the weekend of the Dolphins game or back to July when the jerseys were announced, and if the algorithms think you're a Philly sports fan, you'll see posts with the People photos & news articles about them (both new and contemporary).
Up until relatively recently, knowing, say, a couple of words in Latin or the definition of a polynomial was a sure sign of high-class education. Now that hoi polloi aren't as easily impressed, you would need a much greater depth to differentiate yourself that way.
But that's hard work. Much easier to shitpost on Instagram.
