I think you'd be better off making it yourself or looking for a cheap pattern. Look for a "safari jacket". It's way easier to get "free" if it's free because you did it yourself - but places like Jo-Ann's often have sales where all patterns are $1, which shouldn't be too much to spend.
You might be able to find one to just buy, too.
