Most people do not know exactly when this phrase can be traced, but they do know the its origin."Ply", being a variant form of "apply", means "to apply, work busily at", and in that sense "ply one's trade" was once used of any kind of occupation. (You could speak, for example, of a tailor "plying his needle"). However, "ply" has a second sense. Of a ship, boat or bus, it means to travel regularly between certain places; and of a porter, taxi, etc, to "ply for hire" means "to attend or have one's stand at a regular place to be hired". ("Ply for hire" is still a technical term in the UK, used in taxi licensing regulations, etc.) Since streetwalkers do indeed "ply for hire" in just this way, it's natural that theirs is one of the few occupations of which "ply one's trade" is still rotutinely used.
