Sherlock

In this scene, Sherlock is dressed in very dark, formal clothing. Usually characters dressed like this would be considered villains, but here it is used because Sherlock is an anti-hero and is not the character the audience directly relate to. The character the audience do relate to is John, who is dressed in very normal clothes, and is usually the one who asks the questions for the audience. Irene Adler is completely naked throughout most of the scene (apart from her shoes, which are red, connoting danger), meaning we can't deduce whether or not she is a villain. Whilst she is naked, she dominates the scene and appears to outsmart Sherlock, however when she puts on Sherlock's coat, the tables are turned and Sherlock has the upper hand. This scene suggests men can be controlled by sex, but will ultimately have power over women, so it plays to stereotypes.
The music and dialogue are very fast and snappy, which parallels Sherlock's character.
