It is not really a disguise, but more of a costume. As everyone thinks Count Olaf is dead, he doesn't really need to go into a serious disguise with a fake voice.
He also says his name is "Count Olaf, but not the same Count Olaf who is wanted for an assortment of crimes." Mr Poe remarks that there are so many Count Olafs.
He is a ringmaster at Caligari Carnival. The top hat conceals his unibrow, and the long trousers and high boots cover his tattoo, but because everyone thinks that he is dead, it doesn’t really matter.
- In the Netflix series, Olaf sings Welcome To The House Of Freaks as a ringmaster.
About The Ringmaster
|“||For the Ringmaster, I had the costume department take a big chunk out of the top hat and then crunch it up and burn it a bit, as if it had been discarded for some terrible reason. Like the previous ringmaster had met some awful demise.||”|
— Neil Patrick Harris on the Ringmaster costume in the TV series
