Re: Now that we know the new Doctor...what´s going to change?
Changing his clothes is fine, and he would hardly be the first (Smith has worn a handful of jackets and at least as many shirts under them, Eccleston had different jumpers and pants, and Tennant had two suits and a few different shirts and ties under them.), but he should still have a signature look the same that all the Doctors have. A few variations on that look is always nice to mix it up, but if you let him change every episode the character looses a bit of the that unearthly icon status.
