Protagonist and antagonist costume representation

I have been looking into different types of protagonist characters to find out more about their costumes and what they connote to the audience. I discovered that character's main attire depends on the type of thriller the film is based on and the themes that are within it. I then decided to focus on particular thriller sub genres and see the sort of clothing and accessories that are used.

Crime Thriller
In a lot of the crime related thrillers that I looked at, the protagonist usually dresses smart and almost sophisticated. Take James Bond for example who in every one of the films has looked 'dashing' in his famous suit and tie. This type of costume works well in these types of thriller films because in a lot of cases the crime requires the protagonist to solve a dead end mystery. The smart outfit symbolises that the character is professional, intelligent and determined to stop whatever evil provokes the innocent people's safety.

On the other hand, in crime thrillers, the antagonist is very different in terms of costume. I found that the so called 'bad guy' in most crime films usually wear a mask to hide their identity which builds mystery. This is certainly the case in the film the Dark Knight Rises with the antagonist Bane who wears a mask during the whole script. It leaves the audience wondering why he wears the mask. This links to one of the first scenes where he says "nobody cared who I was before I put on the mask," which strikes us as somebody that wants to be noticed and recognized as an evil figure. I also noticed that antagonist characters mainly wear dark clothing which maybe implies they try to stay hidden.
