It is possible to make longer hair look like a short style with some creativity and this one looks great with a fedora hat. The hat is white with a black band and a fringy edge for the brim.
Take sections of hair and twirl them around and fasten with bobby pins on one side for a look similar to this one. One could add a clown nose like Melora here at Ringling Bros. & Barnum and Bailey and Starlight Children's Foundation "Fully Charged" Premiere if a costume is desired.
