It was the last Sunday -13th Nov - study WT. (September 2016 study edition of the WT) Article entitled:-
"Does Your Style of Dress Glorify God?" paragraph 17.
It is of course written so you can have hours of endless debate but here in my patch of the UK (Southern England but not on Bethel's doorstep) this article has been read as slackening control. I even heard that one nearby body of elders nearby discussed the article and relaxed their "no beards" rule for appointed men.
