A Halloween Costume based on Frankenstein'S Monster from Mary Shelley's Frankenstein. Usually it's based on the version portrayed by Boris Karloff in the 1930's Hollywood films featuring the character, though more modern Japanese costumes have the Screw In Head rather than in the neck like that version.
Only tag Frankenstein'S Monster (Cosplay) if the art explicitly references the story of Frankenstein or the adaptations of it.
