This sort of coat has remained fashionable in the decades following the World Wars. Due to their original role as part of an army officer's uniform, the trenchcoat lent a businesslike respectability. And that's why it's generally excepted that the trenchcoat can 'class up' your outfit! ;)
I don't know exactly who's seen by the real inventor, but for me it's 100 % Burberry. I'm looking forward to the day when I'm one of their lucky-trenchcoat-customers. Until then, I have my Tommy Hilfiger version that replaces the one that I had from Zara... My wallet wasn't so happy with the investment, but I promised him that I'll use this one for years! (or definitely until I'm able to buy one from Burberry).
For the occasion some british inspired pictures. Enjoy!
