A person who identifies as non-binary chooses to wear clothing that is traditionally associated with both masculinity and femininity while expressing their identity through various social interactions. Which category does this example best fit into in the context of performing gender?

The example of a non-binary person wearing clothing associated with both masculinity and femininity best fits into the category of gender expression. Gender expression refers to how individuals show their gender identity through their appearance, behavior, and interactions with others. In this case, the person is using clothing choices to communicate who they are, blending elements from both traditional gender norms. For instance, they might wear a dress with sneakers, combining styles that are usually seen as feminine and masculine. This shows that gender is not just about being male or female; it's a spectrum where people can express themselves in many unique ways.
