I have a jacket like that which is a 3/2 roll and is half lined as l understand it , it was a decent fit from the get go and is darted and made by a company called Kaiser . I wore it a couple of times last year on one of my visits to England( back when we almost lived in a free country) and got complemented on it a couple of times . The thing l love about it is that , it is very versatile and easy to match other clothes to it . .
I like the button through too , it's just not a colour that l would wear personnally.
