We have started to think about costumes for our characters. At the moment there is going to be two main characters, a man and a woman and after they break up the man turns nasty and he starts stalking her. So we think that the man should be wearing dark clothing to represent this, and maybe to show that he's trying to avoid her seeing him.
As the woman is going to be a "damsel in distress" type character, her outfit should be feminine and innocent, so maybe a light coloured top such as pink or white to show the stark contrast between the dark coloured clothes the man is wearing.
