In November 2020, musician Harry Styles made history by being the first male-identifying person appearing solo on the cover of Vogue. His fashion choice of wearing a full-length gown for the featured photo, however, sparked great controversy. Many people showed support for his attempt to defy gender norms through his fashion. However, many also criticized it. The criticism ranged from questioning the ‘appropriateness’ of it, calling it “a bit weird,” to more homophobic sentiments, some even declaring it “an outright attack” on masculinity and social norms (Heyward & Ries, 2020). Certainly, this was not the first time Styles started a debate about normative gender expression through his sense of fashion. Such debates are always surrounding one’s sex, gender, and sexual orientation, especially when one departs from gender and/or social norms. This raises an important question: what are our current understandings of the concepts of sex and gender, as well as their interwovenness within oneself and one’s interaction with society? Before explaining sex and gender, we must address both the sex binary and the gender binary and our understandings of each one. Sex and gender are often thought of as categorical differences, e.g., male versus female. This particular binary epistemology goes back to the ancient Greeks and can be best illustrated by this quote by Aristotle: “as between the sexes, the male is by nature superior and the female inferior, the male ruler and the female subject; this principle, of necessity, extends to all mankind. Where there is such a difference as that between soul and body, or between men and animals [...] the lower sort are by nature slaves, and it is better for them as for all inferiors that they should be under the rule of a master.”
