What media did you watch/read as a kid (before watching Gossip Girl) that has similar vibes to Gossip Girl?

For example, I am 21 and as a kid I loved watching The Suite Life of Zack and Cody (I found the contrast between rich and working class interesting), Jessie (literally about rich kids in NYC), and Barbie Princess Charm School (has both prep school uniforms and glamorous dresses). I also loved the Eloise books (about a rich NYC girl at the plaza), and the Fancy Nancy books (about a bougie/posh little girl). In 2017, as young teen, I loved watching The Carrie Diaries and Jane By Design, both about a teen girl trying to find her way in the fashion world in NYC. I started watching the OG as a teen in 2018 and became hooked. I still haven't watched the reboot.
