Thanks to Doctor Who on facebook, I found this series of articles on how to dress like the various incarnations. In, and of, itself, this is fun! But... as you head on through the Doctors, the insight into their characters is fascinating.
So, make a start... find out how to dress like the First Doctor.
There's a bit of an oops after the Sixth Doctor... the post just says 'coming soon'... so here you go: Seventh Doctor.
Or, you could be boring and read in reverse order from this link.
PS You HAVE to watch the vid at the end of How to Dress like the Fifth Doctor.
