EG chelsea jacket arrived. Nice mid-weight canvas fabric, thought it might be lighter weight and more of a summer version from the pics, but this is better.
Still working out all the button configuration possibilities, think the top one is best.
Some seller on rakuten that I found searching on FromJapan. I regret not picking it up from context earlier too, especially because I live in freakin' Wisconsin and I could've just drove an hour to check it out in person. Oh well, better late than never I suppose.
