The character of Bellatrix Lestrange is everything an evil witch should be: treacherous, conniving, completely without morals, and with a bit of uncontrolled lunacy—not unlike this intricate maze of lace. A large collar wraps the neck and front, and rounds the bottom to become the hem, creating an airy cocoon of interlocking pattern, suitable for witches who love to knit.
Typically, cloaks have no sleeves, yet adding them is more practical for modern witchery.
