The Doctor hadn’t imagined that you wearing a skirt would bother him so much. That’s not to say that he didn’t like it. He did like it. That was the problem - he liked it too much. It wasn’t even that short of a skirt, either. There wasn’t anything overly sexy or promiscuous about it. That, he would have been able to ignore. He had been ignoring flaunted sexuality all his lives (it never failed to make him uncomfortable), and it came easily to him at this point. But you weren’t flaunting anything. You were in a tasteful, flowing skirt that cut off right at the knee. It flared out a bit whenever you turned, giving just the slightest tease of your lower thigh, but there was no inappropriate exposure. None at all. It was perfectly perfect. But the Doctor was scared of it.
“Wait a minute. What are you dressed like that for?” he asked when you finally joined him in the console room. He immediately bit his tongue when he realized how he sounded, but… he really wanted to know why you were wearing that… thing. And heels. Oh, no, you were wearing heels. They weren’t especially tall and the wedge was hardly more than an inch, but this was more heel than he had ever seen you stand on.
You made a silly face at him in response, too accustomed to his non-ginger rudeness to be offended. “Is this alright for where we’re going? I’ll just change real quick if it’s not. I just never get to wear it.”
That’s right, you never got to wear it. (Forget the heels. Can’t run well in those, so they were out of the question.) The Doctor had never seen so much leg on you. You wore trousers, always, because you were smart enough to know that skirts were not for adventuring. Even in hot weather, though, you didn’t wear shorts. You just wore trousers with thinner material. Shorts were nice, but the idea of running through dense underbrush or stinging nettles or a bog with bare legs didn’t appeal to you, so you kept your legs safely covered. Until today.
