Another excellent media genre that people can get ideas for funny Halloween costumes is modern music. Modern music has many sub-cultures and each subculture has its own unique fashion statement that is easily identified with them.
Heavy metal rock is an excellent fashion culture that easily fits in especially with the grotesque traditional Halloween theme. Anything from Metallica to Kiss captures Halloween vibes.
Another excellent music genre to include is techno, especially when taking references from unusual get-up of their recording artists such as Moby and The Prodigy.
Lastly, Rasta fashion of reggae music can fit in as much as they do in all festivities due to their sharp party colors.
