Femininity (also called feminity, girlishness, womanliness or womanhood) is a set of attributes, behaviors, and roles generally associated with girls and women. Femininity is socially constructed, but made up of both socially-defined and biologically-created factors. This makes it distinct from the definition of the biological female sex, as both males and females can exhibit feminine traits. People who exhibit a combination of both masculine and feminine characteristics are considered androgynous, and feminist philosophers have argued that gender ambiguity may blur gender classification.
