> Easton Ellis portraying how materialistic the yuppies were with his narrations is engaging too. Learnt more high end brands reading this book. And the other thing is where most of them confuse Patrick Bateman with someone else I think it’s a nod by Ellis saying that most yuppies are unrecognizable from each other, living the same identical life, and making the yuppie lifestyle their whole identity (just my guess btw).

Don't downplay your interpretation, it's a really good observation!

Ellis (Easton is a middle name FYI) uses Bateman's obsession with the minutiae of the brands he wears as a way to show us how desperate he is to fit in. Bateman even tells us precisely what brands he uses in his skincare routine, and how many of his peers are going to notice that? It's all about buying into the eighties consumerism idea that certain brands will give you a certain lifestyle. It's not an idea that's really gone away either, cf. influencers.

You might have seen as well the theory that all the murders and violence are in fact in Bateman's imagination and didn't really happen. I'm not sure which side of this debate I'm on, but ultimately I don't think it matters that much. Whether he's a serial killer or "just" deeply mentally ill, his so-called friends don't care as long as he's fitting in. On quite a few occasions he tells them things he's done (or thinks he's done) and it's not often clear that he's been heard, and even when he has, his friends joke about and misinterpret his comments. He wears the right clothes, eats at the right restaurants, and takes the right drugs, so who cares about the odd little murder or psychotic break?
