Guys, I was watching this PBS documentary on Netflix called "The Secrets of Her Majesty's Secret Service" today and they were interviewing this former MI5 agent turned author named Matthew Dunn who looked to be in his late 40's or early 50s. In the camera shots were he was walking the streets of London, Dunn was walking around with ONLY the bottom button of his blazer buttoned. Whats the deal with this? Do some people actually walk around with only the bottom button buttoned, or is this just one of Matthew Dunn's fashion idiosyncrasies? I've never seen anyone else do this, not even on a fashion-forward designer's runway show look.
