Planning costume ideas:
The name of the film is Mia as because the main characters name is and the film mainly revolves around her. It also gives a weird vibe to the film as it makes you wonder if it's the name of a person or a place which may be isolated and dangerous, as Mia later on is isolated by her boyfriend and close friend and then is in danger with the stalker.
