Fan Steve Whiting said: “It's very different to what we've seen before and has great elements from previous Doctors.”

Whittaker, who starred in Broadchurch, takes over from Peter Capaldi and will make her debut on screen when the Doctor regenerates in the Christmas special on BBC One.

The new series will air in the autumn.

When she was announced as the next Time Lord, the actress urged fans not be “scared” of her gender.

Asked how it felt to be the first female Doctor, she said: "It feels completely overwhelming, as a feminist, as a woman, as an actor, as a human, as someone who wants to continually push themselves and challenge themselves, and not be boxed in by what you're told you can and can't be. It feels incredible.

"I want to tell the fans not to be scared by my gender. Because this is a really exciting time, and Doctor Who represents everything that's exciting about change. The fans have lived through so many changes, and this is only a new, different one, not a fearful one."

In a trailer that was released at the time, Whittaker was seen in a dark hood and long grey coat - but said that would not form part of her official Doctor Who outfit.
