Howling Ii Your Sister Is A Werewolf (1985)

Howling II: Your Sister Is a Werewolf is the 1985 horror sequel that swaps suburban werewolf attacks for gothic nightclubs and pagan ritual. Sybil Danning stars as the werewolf queen Stirba, and the archive holds 2 scenes pulled from the film showing her topless and fully nude on screen. One of those clips is the ritual sequence where she rips her top off mid-transformation, the scene people come here for.
