In the original film, Leatherface wore three different masks: the "Killing Mask", "Old Lady Mask" and "Pretty Woman Mask". Gunnar Hansen commented: "The reason he wore a mask, according to Tobe and Kim, was that the mask really determined his personality. Who he wanted to be that day determined what mask he put on. So, when Drayton comes home with Sally, Leatherface is wearing the 'Old Lady Mask' and he's wearing an apron and carrying a wooden spoon, he wants to be domestic, helpful in the kitchen.
At dinner he wears a different face, the 'Pretty Woman,' which has makeup." Also of note, the 'Pretty Woman' outfit consists of a female wig and a black suit, as Leatherface is "dressing up" for dinner, an old deep south tradition which stems from his southern upbringing, and the 'Killing Mask' is the skin mask he wears while chasing and murdering captives. Tobe Hooper also discussed the multiple masks and dinner scene on the audio commentary for The Texas Chainsaw Massacre.
Hansen later added, "The idea of the mask is that there is no personality under the mask. That was the idea in talking with Tobe and Kim. When they created the character, they said he has to put on masks to express himself because he himself can't do it. The way we tried to create him, there is nothing under the mask, which is what makes him so frightening
