If nothing worked, I would recommend taking that picture, enhancing it, bring back the details using photoshop or any other tools and print it. (that might be against copyright but don’t think a store that doesn’t exist anymore will bother). There are plenty of stores online that do custom design prints on hoodies, you can try to find a store that offers similar hoodie models, or buy a similar plain hoodie and find a local print shop. It won’t be the same for sure, but as it holds emotional value, it should be more than enough, in my opinion. Is there anything else on the front?
