Her dress is made of dimensional fabrics that allow for whatever is underneath to traverse the dimensions and allows she and whatever she wraps in her dress to warp. She is able to control her dress as an extension of her own will and body. Her eyes are a deep dark violet and her dress is typically black and gray and very ornate. Her style is more the ‘gothic-lolita’ style, befitting of a half-ghost girl, though it is a regal gothic style. Despair's dress/cloak has a special ability to deflect elemental attacks and her cloak/dress has the ability to stretch, change shape and teleport (Similar to Zeon from Zatch Bell or Laharl from Disgaea), since it is made of an otherworldly, dimensional substance. This cloak is indestructible and unable to be ripped or torn, since it is not made of a material that tears or rips. When her legs are present, she is known to wear short, but very impressive ankle boots.
Everyone knows what a straight razor looks like, and she just looks like a normal one, so yeah.
