Costumes

This would be similar to the dress that my main protagonist would be wearing in the original opening to my film. It would have been a sophisticated black dress, not necessarily with a single strap.

This will be worn through the whole of the film by the main character and gradually it would get ripped and have tears in. Hopefully it would create a juxtaposition between  how she is seen to the audience at the start of the film and how the audience sees her at the end.

This is similar to what the dress would look like at the end of the film. As you can see, it has noticeable rips and tears to it and is not as pristine and sophisticated as the original dress worn at the beginning.
I feel that the contrast between a pristine outfit and the ripped outfit is kind of a cliché in the horror genre. However, I believe that it is a classic cliché.
