Zipperface (1992)

Dona Adams is Lisa Ryder, a police detective assigned to investigate a series of murdered prostitutes in the kinky slasher-mystery flick Zipperface (1992). The murderer, whose identity is unknown for most of the film, wears an S&M leather mask with a zipper for his eyes as he stalks and kills his unfortunate victims, none of whom get naked. But we do get to see Laureen E. Clair in her lingerie. And that will put the cream in your pastry.
