I also thought that he would wear a red piece of clothing what piece of clothing that is hasn't been decided yet an the reasoning for this is that the colour red symbolizes danger so we are trying to reach to the audience and signal to them that he is the one who is carrying the threat the one who is causing danger below is just some example of red pieces of clothing.
I also felt that him wearing some clothes whether it be a jacket or shirt but i thought that it could be ripped up , this showing the audience just how crazy he is and making them think what has been done for his clothes to look like that and what may happen next from this character.
This character is quite reserved and likes to keep himself to himself ( a man of few words) but that can quickly change and so can his attitude and actions he will be very short tempered and anything can flip his mood , along with the red piece of clothing worn by him the fiery attitude will also be a sign of how dangerous he can be.
I also thought that this character may wear a straight jacket the significance of this is to show the real dangers of this character and show to the audience just how dangerous he actually is
