Where can I get Mystery's black furry hat from the pick up artist?

For kicks I am going to by Mystery from VH1's pickup artist for Halloween. I need to find a large black furry tophat/bucket hat. Does anyone know any stores or online sites where I can find the same hat? Most of the ones I've seen aren't big enough. It has to be unproportionally tall.

This is the closest hat I found but it looks like it's for a girl, would this work? -
