Jodie Whittaker is about to take over the role of Time Lord when ‘Doctor Who’ returns in just a few days! Whittaker has given fans something to mull over; the inspiration behind her Doctor costume, which she co-created with costume designer Ray Holman!

Whittaker explained that she brought Holman “lots of images and bits and pieces” she’d seen online to their initial meeting. The images included album covers from the band Coldplay and an image of a “non-gender specific woman in a T-shirt, cropped trousers and boots.”

In a recent interview, Whittaker detailed how she started to create the look in her mind, saying:

“I found an old black-and-white image on Google that spoke to me. It’s of a woman walking with purpose in crop trousers, boots, braces and a T-shirt, and she just looks so comfortable and non-gender specific — that was my style point.”

As for the rainbow T-shirt, that part was partially inspired by Coldplay’s cover artwork. Whittaker explained:

“I need it [the costume] to have colour because I respond to colour. I really love the use of colour on Coldplay album covers, which I also showed to Ray. Which is where the rainbow came in — nothing evokes a sense of hope in me more than hundreds of rainbows!”

Whittaker has worked with Holman before during her days on ‘Broadchurch,’ and told him she wanted her costume to be “comfortable” and “practical and said, “I certainly needed pockets.”

Whittaker also revealed the hidden message behind the long blue coat, saying:

“Ray [Holman] had the idea of my coat representing the sky — so the exterior is day but the lining is dark blue for space.”

It would seem our new Time Lord kept some things to herself though, as she cryptically said:

“One day I might be able to tell you what it all means, but for now everything is a secret between me and Ray, so I’m not allowed to say.”

‘Doctor Who’ returns to the BBC on Sunday, October 7!
