The character and look of The Shadow gradually evolved over his lengthy fictional existence.
As depicted in the pulps, The Shadow wore a black slouch hat and a black, crimson-lined cloak with an upturned collar over a standard black business suit. In the 1940s comic books, the later comic book series, and the 1994 film starring Alec Baldwin, he wore either the black slouch hat or a wide-brimmed, black fedora and a crimson scarf just below his nose and across his mouth and chin. Both the cloak and scarf covered either a black doubled-breasted trench coat or regular black suit. As seen in some of the later comics series, the hat and scarf would also be worn with either a black Inverness coat or Inverness cape.
