Do you know that we ( I was born and raised in Japan )call this kind of jacket “COVERALL” , most likely in historically accurate blue denim or hickory stripe or ……cotton duck.
And, I know “COVERALL” is a shortened Japanese version ( Japanese like to shorten ) of the word “ COVERALL JACKET” which some Japanese started calling them in 1970s for unknown reason.
I think “COVERALL JACKET” is not a bad name. I believe that “ COVERALL JACKET” name could have stuck if some American company had named it so in the history.
I almost lost what I was trying to say here…….well, I believe that’s a good name despite the fact that American did not create it! ( Takeshi )
