I was on a panel about the thirteenth Doctor at the Farpoint convention back in February, and when we were talking about the costume, which had been revealed at that point, and I said something like, "I wasn't sure about the costume at first, but the more I looked at it and thought about it, the more it made sense to me as a Doctor outfit. Maybe it's the boots, but I keep thinking that it's a Matt Smith-style costume." And then a woman in the back of the room, a look of shock on her face, exclaimed, "Yeah! Matt totally would have worn that!"
The problem we have at the moment is that we don't know how the costume "works" in motion. Still photos don't really sell it. I've seen art sketches of it that make more sense.
That said, I still wish Jodie Whittaker could wear the Capaldi costume from "Twice Upon a Time." As the leaked clip shows, she really rocks the suit, much as Lucy Liu rocks her suits on
Elementary. Yet I recognize that she needs her own, defining look, and aping late Capaldi wouldn't be a good branding move.
