There are 2 main points in Mulvey's male gaze theory.
This theory suggests that women are objectified by portraying them through the eyes of a heterosexual male. The reason this is believed to be done is to entice the audience, it plays on the way that men look at women as well as how women look at themselves and compare themselves to other women. To portray women in this way, the camera lingers on their curves and portrays events through the male reaction rather than the females actions.
People are more focused on the women dancing around that they are unlikely to notice things like this in the background of the video.
This part of Mulvey's theory exclaims that women can be me presented as one of two things.
As an audience we are drawn to these characters. Female artists that represent this contrast are Taylor Swift as the innocent virgin and Lady Gaga on the opposing side.
