Gender expression typically reflects a person's
gender identity (their internal sense of their own gender), but this is not always the case. Gender expression is separate and independent both from
sexual orientation and
sex assigned at birth. Gender identity can be expressed through behavior, clothing, hair, makeup, voice, body language and other aspects of one's external appearance. Gender expression does not always fall in line with a person's gender identity. A type of gender expression that is considered atypical for a person's externally perceived gender may be described as
gender non-conforming. Gender expression can vary widely between individuals and cultures, and may not always align with traditional
gender roles or expectations. In men and boys,
masculine gender expression is often described as
manly, while atypical or feminine expression is known as
effeminate. In girls and young women, atypically masculine expression is called
tomboyish. In lesbian and queer women, masculine and feminine expressions are known as
butch and femme respectively. A mixture of typical and atypical expression may be described as
androgynous. The term
gender expression is used in the
Yogyakarta Principles, which concern the application of international
human rights law in relation to sexual orientation, gender identity, gender expression, and
sex characteristics. The term also part of the criteria for human rights protection in certain countries, including Canada. == Versus sexual orientation ==
