Trying to recreate a casual mid-century country look.

I am looking to recreate a mid-century country look that's more casual than that of a country gentleman (tweed, trickers, and flat caps). Please let me know where and what to look for (e.g. brands and items).

If I haven't been clear enough, a picture of the Frenchman from Inglourious Basterds is attached below for visual reference.

Sorry for creating such a general thread, however I couldn't find what I was looking for using the search function.

Thank you!
