I didn't mean to imply that the situation re: blue jeans in my neck of the woods was universal, although what I wrote could certainly be taken that way. I should have been more specific. I'm not sure exactly when the policy changed in my elementary school; I think by the time I was grade five or six, blue jeans were tolerated. By the time I was in grade eight, I think girls were allowed to wear jeans. This was in the 'sixties.
