Personally, I’m most excited to meet Fifteen. Every promo pic of him makes him look cooler than the one before. (If absolutely nothing else, he has fantastic fashion sense-- guess the reason all the other Doctors were so fashion-oblivious was because he was hogging it all for himself, lol.)
You mentioned it in your post, but I’m psyched that RTD seems to be giving style and historical fashion more of an emphasis this season. It’s new and I think the promo images look great.
