This statement is really kind of funny, because its so stylized, so absolutely stereotypical that there was no way for you to possibly come to it creatively and originally.

Is some one buying momjeans on depop brainwashed, or is it you? If you aren't the one who is brainwashed why is your reply so ritualistic?

I think you're mixing up self-expression and being completely unique. Self-expression is about fitting in as much as standing out. It's about figuring out who you are, and how you fit into society. Fashion is about telling the world "this is who I am". It's a really good way to connect with like-minded people.

If you wear a business suit, you'll find company with conservative business people. If you wear all black, heavy boots, and band t-shirts you'll find company with people who are into the local music scene. If you wear Patagonia vests or startup hoodies you'll find company with people who want to code into the evening.

If your interpretation of fashion is "looking like others" then it means that your last encounter with fashion was when you were a high school teenager.
