>>7662131 (OP)I don't buy chinkshit anymore but aliexpress and the other chinese seller websites are still a great reference for a lot of weird clothes and other items that you might want to put on more fantastical characters. They're often not worth buying for this purpose as irl is a bit different from their photos (plus the shipping time).
Beyond that you can try going into thrift stores and buying things exclusively as reference material and props to study. You may need a mannequin if you don't know anyone who can wear and pose it for you though. Lights aren't that costly but they're also a thing to remember. These are writeoffs.
Hobby stores also have lots of little dioramas set up, usually, that you can reference for various things if the owner is fine with you bringing your sketchbook or tablet in to work. The lighting can be an issue, however.
Besides that you could try just anywhere "interesting people" go for extended periods and draw them. Libraries and coffee shops are the classic ones but at least in my area they're a bit more normiefied now.
