Help please im a teenager who wants to shop alternative clothing ethically

Hi there! I love alt fashion, I’ve dressed like it my whole life, but lately the world has been crumbling apart and nothing is ethical anymore! Everything is either fast fashion, supports trump, or is just bad. I used to shop from hot topic and Spencer’s but now thats bad too! Also brandy Melville, Hollister, Abercrombie and fitch, like, nothing is good. Im located in south florida and am a teenager who is looking to stop being a poser! (I feel like i am one because i keep shopping at unethical places, but its really hard to not) Of course I’ve shopped through thrifting, eBay, vinted, depop, poshmark, and up cycling, but you know, it gets to a point where ill just strugggggle a lot. If anyone has any recommendations other than places like eBay, I’d appreciate it so very much!!!
