If you really feel inclinded to pretend you are from the country, atleast hit Lester Bowden who have a superb Crew and Barbour selection.
The overall look is a bit Tatler's 'Bystander' (which I will feature in one day in the near future) - the messed up hair which ironically takes longer to achieve and has to be clean for it to work, and natural 'flushed look' make up, which suggests you spend a lot of your time occupied with outdoor pursuits.
The accessories: Louis Vuitton bag, Dolce and Gabbana sunglasses and nude heels (I couldn't help myself okay, I left my wellies in my country home anyway)
