In my country a few years ago there was the (unwritten) rule that skirts long to the shoes were not OK for sisters. Unfortunately in Brooklyn it seems that nobody knew about this, so once, much to the embarassment of the local branch that was upholding the rule, a WT issue came up that had on one page a pic of a sister preaching who wore just that kind of skirt; and on another page a pic of a Witness party with a sister sitting on a sofa whose skirt covered her shoes. Result? The issue in the local language was printed with "edited" pics: the pic with the preaching sister was added an edge of greenery at the bottom so you could no longer see where the skirt ended; in the other pic they did a better job in that they actually shortened the skirt and added feet and shoes.
Don't know if the changes were approved by the Headquarters or were an independent initiative of the branch committee. Anyway I saw the changes with my eyes as at the time I had access at the English issue of the magazines.
