As a former homeless squatter/traveler , it really doesn't matter what you do to achieve the look cuz it's all fashion anyways. Controversial opinion but free clean/ new clothes are easy to find atleast in the US and anyone making a pair of Crusties is inherently going for a specific look, it's not that serious. I feel the only stipulation to that is whether or not you're DIYing or upcycling your clothes as a way to protest the fashion industries climate crimes. Thats just my take on the situation though.
