While anyone may wear clothes associated with a different sex, the term cross-dresser is typically used to refer to heterosexual men who occasionally wear clothes, makeup and accessories culturally associated with women. This activity is a form of gender expression, and not done for entertainment purposes. Cross-dressers do not wish to permanently change their sex or live full-time as women. Replaces the term transvestite.
