Why are the outfits on fast fashion sites so much cuter and how do I find alternatives?

Yes yes, everyone knows about fast fashion. It’s something that’s definitely been talked about way too much on this subreddit, but like, I’ve been having a problem with it. The best way to describe it is that in my opinion, the outfits on places like Shein legit look so much cuter than the stuff you’d find at a normal clothing store or on somewhere like Amazon. Maybe I just haven’t found any good places, or maybe my location just sucks, but like, as someone who’s huge on alternative clothing, like goth (elements of legit and modern) or grunge or the “e-girl look” or any of the other things (overall just depends on my mood and situation of the day) it’s just so hard to find stuff that’s as cute as the cheap stuff while still being, yk, not made by child labor.

Since I’m sure this has been a question asked before (hopefully 😭) I’m sure the best answers should be pretty straightforward. So like lemme know that best websites or apps or irl stores (so long they’re in the Southwest US lol) for overcoming this. And ofc thanks for any recommendations.
