Through most of the film, Trisha wears furry boots. After the killer captures her, we see her tied up in the basement with bare feet, but when she frees herself and runs from the house, Trisha is wearing her furry boots again.
When she is making out with Matt on the living room couch, Trisha is clearly wearing a bra. Later, after taking her to the basement and tying her up, the Madman opens Trisha's sweater exposing her breasts. She's no longer wearing the bra.
