Costume research and planning for film opening

In our film opening the costumes we are going to want to use will vary across the two different main characters. Ben the victim will be wearing normal clothes as he has just come home in every day life, he is simply returning home. He will be wearing jeans and trainers and a jumper/coat and just a jumper when he gets indoors. The murderer however will be dressed in dark clothing to aid the horror genre, the lighting in the room will be dark and we want the murderer/demon to be only seen vaguely. He is going to also be wearing a mask to aid to the scariness, possibly a mask looking like an old person from a hospital institute or a mental patient looking mask to add to the scariness of the opening. I found a couple of examples of masks that we as a group discussed to be scarier than most others and ones that would look scary and not unrealistic in the film.
