Vampire at Midnight (1988)

"Jenny is played by the one-and-done feature film credited Lesley Milne in a rigid performance that’s critically subsided by her well-defined figure."
Lesley Milne dropped out of acting after this film and went on to be a local TV weathercaster.

Continuity Error: This original 4:3 format clearly shows from the front view that Milne is wearing panties when her gown is removed. But the cut to the back view shows her bare ass and no panties. Later widescreen versions on DVD cropped out the panties so it seems like she was fully nude.
