Two that jump out for me is George of the Jungle when Leslie Mann got wet fully clothed which was an early favourite.
Another is one of Texas' music videos. Something about about the vocalist in her wet red t-shirt just hits the mark for me

Malcolm In The Middle, when lois gets soaked by the neighbours sprinklers. Quite possibly influenced my interest in wet clothes.

Marcia Cross in an early season of "Desperate Housewives" getting caught in sprinklers.
