The Ghostface costume is the costume worn by the killers in all three "Scream" movies. It is also referred to as Father Death or Scream. The mask is loosely based on artist Edvard Munchs painting The Scream. The mask is stark white and depicts a caracature of someone screaming and crying at the same time. The rest of the costume is a plain black robe with fake tatters hanging from the sleeve.
The costume is also available as a Halloween costume, generally made of cheap fabric like many Halloween costumes, and with a robe that is put on by slipping it over your head like a shirt. The movie version, as well as being made of much sturdier fabric, is put on like a jacket and fastens down the front with velcro. The mask is the same with both versions.
