I actually saw a jacket that resembled Leon's for a while at Fred Meyer. I don't know if it's still there, I would have boughten it, but it was way too big for me. I also see jackets that resemble Leon's at Goodwill a lot. You should try looking around there for a little bit, and see if you find anything.
When I shop at Goodwill or Value Village, I always bring reference pictures with me either on paper, or on my phone, cause there's a lot of things I tend to forget, like small details or obvious ones, so it's always good to bring those.
