A darker variant of our popular "Valkyrie" taffeta, this bewitching green-and-black amalgamation conjures imagery of witches meeting together to amplify their collective magical energy in order to cast complex and powerful spells!  The concept can be traced all the way back to Renaissance art depicting groups of witches, including the three "weird sisters" in Shakespeare's "Macbeth," while the word itself dates back to 1921 when noted British anthropologist and historian Margaret Murray claimed that all witches across Europe met in groups of thirteen, which were called "covens."
