One of mine is in high school, and as much as I hate the confirming culture, especially because it's led by morons and marketing, I choose the same path. I allowed my (now high school kid) to participate in all the awful crap that I would never do myself when she felt middle school pressure. She was in the popular kids group.
The caveat has been it all comes with extreme education from my end. Not demeaning or condescending. I over-preach about marketing/ads/influencers and constantly question why people make the choices they do. I question everything though. "How do you know that?" often leads back to tick tock.
In my experience, the OTHER kids are now getting smarter as they age. Mine is now able to live her life how she wants and is still with that same group , and the kids (I shit you not) look to her for purchasing advice. The vanity kinda goes away as their brains leave that dumb social hierarchy age.
Note: My kids are/were decked out in Nike. We live by the world headquarters and a good chunk of the kids' parents work there. If that isn't peer pressure, I dunno what is!
This apartment isn't big enough for the two of us and your constant eating of beans. You know why
