This article caught our eye on Mens Journal, because we really respect Sunspel as survivors who still manufacture in the UK (they still have a factory in Long Eaton, England, where they’ve been based since 1937).
We thought this quote was interesting for the differentiation between Englishness and Britishness:
We are English. And that's about a certain type of attitude. I think this is why it should resonate with Americans. Englishness is about a belief in liberalism, and individualism, and the right to be eccentric or do what you believe personally which is, in a way, completely the opposite of Britishness, which is being told to do this or that. Englishness is about taking the piss.
