transvestism

Transvestism was a medicalized framework primarily used in the late nineteenth and early twentieth centuries to classify and explain varied forms of gender-variant expression and behavior. Coined by Magnus Hirschfeld in 1910, the term included a diverse range of phenomena that later came to be understood separately as cross-dressing, aspects of homosexuality, eonism, transsexuality, and transgender identity, but was not limited to any single one of these concepts.

During the mid-twentieth century, transvestism was classified as a psychiatric disorder in diagnostic manuals. As medical and social understandings of gender variance and gender identity evolved, the term became increasingly outdated, stigmatized, and largely replaced by other terms. In its place, several more specific terms emerged, including the neutral, non-medicalized term cross-dressing for clothing choice behavior, alongside clinical terms such as transvestic fetishism which were retained for narrowly defined psychiatric diagnoses.
