I remember that study. I also remember those Brits always wore the same tie daily. I wear scrubs, with running shoes daily at work. The community standard of medicine in Phoenix allows for this. On the east coast, I probably would stick out. If I wear a shirt and tie with white coat, my colleagues and patients would ask me if: 1) If I had a TV interview; or 2) If I had a date with my wife; or 3) Do I have to go court (j/k). My kid brother who lives in Seattle and is also a physician was shocked that I dressed this way daily. He wears coat and tie daily and changes to scrubs only to operate. My older brother who is also a doc in Southern CA dresses in the middle (business casual). I guess you just got to know the market that you are serving.
