Magazine Front Cover

Bella Hadid is represented as a confident, beautiful woman who knows what she wants. Things that challenge the stereotypes in this cover could be the way in which she's dressed. It looks like she's wearing a top which doesn't show her cleavage, usually most magazine covers show this to attract male gaze, also, her hair is slicked back which also goes against  stereotypes as you usually associate males with slicked back black hair. 
Things that reinforce stereotypes are how thin the model is, you can see her arms are really thin which reinforces the stereotype that women look pretty when they are thin. Her makeup is really natural which shows she is naturally beautiful. Also, the way her finger is in her mouth attracts male gaze as it looks sexual. The shot is mainly focusing on her arms and face which again attracts male gaze. She is represented as a young american woman from a high class.
