The legendary vampire’s association with formal evening wear arose not from the original 1897 novel but from a 1920s London stage adaptation by Hamilton Dean. The evolution is described in Bram Stoker’s Dracula: A Reader’s Guide:
Another major innovation was the styling of the Count as a gentleman in outline rather than as an instantly recognizable degenerate. Deane’s vampire wore contemporary evening dress – the white tie, tail coat and opera cloak that remains a signifier of vampirism to the present – rather than the frogged frockcoat of Graf Orlock [the vampire in the 1922 unauthorized German adaptation Nosferatu], or the unexceptional dress effected by Stoker’s Count . . . The vampire is now not merely a figure so unexceptional that it could move without comment across London, but it is also aligned with the establishment, with domestic signifiers of power and wealth rather than with visible foreignness.
Beginning in 1924 Dean’s adaptation toured Britain successfully before arriving at London’s West End in early 1927. It was here that an American impresario obtained the rights to revise the play and bring it to Broadway later that year with Hungarian actor Bela Lugosi in the title role. This casting signalled a further significant change to the already modified Count of Dean’s production as described in Hollywood Gothic. The Tangled Web of Dracula from Novel to Stage to Screen:
The London Dracula was middle-aged and malignant; Lugosi presented quite a different picture: sexy, continental, with slicked-back patent-leather hair and a weird green cast to his makeup – a Latin lover from beyond the grave. Valentino gone slightly rancid. It was a combination that worked, and audiences – especially female audiences – relished, even wallowed in, the romantic paradoxes.
Though not the Universal Studio’s first choice, Lugosi was signed to play the vampire in the first authorized film version of Dracula, released in February 1931. And the rest is vampire history.
