The endearing, cowardly Nardole (Matt Lucas) was a brief companion of the 12th Doctor on the BBC TV series Doctor Who. Originally an employee of the Doctor’s wife, River Song, Nardole lost his head in an attempt to discover River’s whereabouts but was reassembled by the Doctor. The two joined forces for a short while, and then Nardole made a courageous decision that lead him down a different path. Nardole dresses in a distinctive, goofy outfit of burnt orange coat, beanie and glasses.

Accidentally drawn onto the Doctor’s ship on her wedding day, Donna Noble never thought she’d see the lonely alien man again. But unable to get him out of her mind, she began searching for him wherever something strange or paranormal cropped up, eventually joining him as a full-time companion.

What can you say about the Doctor that hasn’t already been said over his show’s fifty-year history? He’s nine hundred years old, he’s an alien and he travels through time and space in a 1963 blue police call box. Also, sometimes he looks like Christopher Eccleston and that’s pretty fantastic.

The titular character on the BBC hit TV series Doctor Who is the last of the Time Lords, a race capable of time travel and regeneration. The Doctor has regenerated its body 13 times, and for the first time it its history it regenerates as a woman (Jodie Whittaker) for its 13th life. She travels the space-time continuum with her companions Graham, Yasmin and Ryan. This guide covers the 13th Doctor’s first iconic – and eccentric – look of suspenders, cropped pants, rainbow shirt and coat.

Malcolm Tucker (Peter Capaldi) is the foul-mouthed and hilarious protagonist of the British series The Thick of It and the 2009 film In the Loop. His clothing style is the basic business look: suit and tie, button up dress shirt, black shoes, black belt. The rest of the character is about getting overly creative with your insults.

The wife of the Doctor and daughter of Amy Pond and Rory Williams, River Song (Alex Kingston) has an illustrious parentage on the BBC series Doctor Who. She first appears as the wife of the 11th Doctor, but because of her warped time line and supernatural abilities due to TARDIS DNA within her she makes multiple appearances across seasons. Professionally she is a Professor of Archaeology, but most of the time she is either seeking out the Doctor or being forced to harm him by his enemies. To capture her image, go for a long tunic with black leggings, wild hair and an infectiously cheerful personality.
