Btw cheap from AliExpress is the opposite of sustainable. Almost guaranteed to be the cheapest/most environmentally damaging materials, fabrication, and shipping systems.
Find a quality thrift store in the wider area if you want to maximize every positive, from the higher quality and lower price of the garments to the environmental impact. And you can feel better about cutting up and throwing away material that has already been used rather than buying a whole new hoodie only to dispose of 30% of the fabric.
Look for consignment shops that buy clothes from people rather than thrifts that just accept donations, cuz that's where people go with their good stuff, but it's all still cheap.
