And the majority of anachronistic costumes -- including those of the 8th, 7th, 5th, 3rd, 2nd, and 1st Doctors -- look really stupid, especially in the modern context.
Yes, and the old Doctor Who used to use cheap, cheesy plastic and cardboard sets, too. Especially for alien settings. Ergo, according to this kind of logic, it is UNACCEPTABLE for them to do any scenes on an alien setting. Because, clearly, there have been no strides in the improvement of set design over the decades.
Translation, since I have a strange feeling you're intentionally going to pretend that you don't quite get the parallel there, costuming has evolved over the years. It's very, very possible to have a tastefully anachronistic costume in this day and age. Why,
real people do it every single day as part of their regular wardrobe. Russell Brand is a fine example. Another is
this steampunky professor.
