I’ve been in situations where I’ve needed to borrow a jacket or a shirt and that usually works out fairly well. As long as the jacket isn’t super small it will usually get the job done. Shoes and boots don’t really work out the same way. If they are too small then you aren’t even going to get out the door. More than a size too big and you are going to leave one behind in a mud puddle. At least you can sometimes make up the difference with an extra couple socks when they are too big.
