Re: 12th Doctor Costume?
Troughton, Tom, Davison and McCoy, were the only ones to wear hats on any kind of regularity.
Well, Troughton didn't really: he wore That Bloody Hat (as it's officially known - yes it is, don't tell me otherwise) in his first three stories but never later; apart from that there's just a woolly bobble hat in Fury from the Deep. Hartnell wore his fur hat or the panama a lot more than that!
