The BBCAmerica’s Anglophenia blog is running a series of “how to dress like the [X]th Doctor” posts, offering guidelines for dressing like the various incarnations of Doctor Who. So far the First Doctor and Second Doctor are up, with the Third and subsequent coming soon.
The suggestions are rather general–along the lines of “find a white shirt” rather than “here’s the exact brand of shirt you’ll need”–so serious cosplayers might be disappointed, but for casual hall costume or Halloween party wear, they’ll be just fine.
I’ll be curious to see what they suggest as a substitute for Tom Baker’s scarf.
