Gender expression

Gender expression is how a person presents gender to the world: clothing, hairstyle, makeup, mannerisms, voice, even the way they walk. Societies habitually read these cues as “masculine” or “feminine,” but expression is a spectrum — and it can be fully decoupled from gender identity and from sexual orientation. A soft-spoken, gentle man may well be a straight cisgender man; an androgynous woman is not necessarily a lesbian. Guessing someone’s orientation or gender from their appearance is the most common misreading there is — and the least reliable (see Can you really tell at a glance?).

Expression is also the axis most heavily policed from outside — “boys don’t cry” and “act like a lady” target expression, not identity. Once you see that this axis stands on its own, it becomes clear why that policing is unfair to everyone, not just to LGBTQ+ people: it punishes any presentation that strays from the template.

Register note: standard in formal and educational contexts. The everyday Chinese near-synonym 性别气质 (“gender temperament”) leans toward describing masculine/feminine vibes and covers slightly less ground.

Common misuse: treating expression as “evidence” of identity or orientation — the SOGIE axes are independent; a man in a skirt is not necessarily trans, and not necessarily gay.
