Transvestite

A Transvestite or cross dresser is a person who dresses in a manner traditionally associated with the opposite sex. In some cultures, transvestism is practiced for religious, traditional, or ceremonial reasons.

Magnus Hirschfeld coined the word transvestite in 1910 (from Latin trans-, "across, over" and vestitus, "dressed") to refer to the sexual interest in cross-dressing.
