Gender expression refers to the external presentation of an individual's gender identity through behaviors, clothing, hairstyle, and other forms of self-presentation. It can include a wide range of expressions, from traditionally masculine or feminine styles to androgynous or non-binary presentations. People may express their gender in ways that align with societal norms or choose to challenge those norms. This expression can vary greatly across different cultures and communities, and it is important to recognize that gender expression is distinct from biological sex and gender identity, which are separate concepts related to how individuals perceive themselves and their physical characteristics.
