There was a time that Doctor Who dressed in a flamboyant style that nobody else would dress in. Since the comeback, the creators have become boring.
Not only do they seem to be unable to do stories that do not revolve around Earth, but they have lost the creative spark as far as his costume goes.

Quite frankly, while the dress sense is somewhat quirky on this gay looking emo, its still far too damn normal.

Look at both Bakers, Troughton, McCoy, Davidson, McGann and Pertwee and they looked out of place in any time, but because of the new series reliance on being set in modern day England, the last three have all been far to conformist.

And going on the assistants dress sense, it would seem she has borrowed her wardrobe from Buffy the vampires slayers Willow, circa 1997.
