George F. Richards recommends the simplification of changing the temple robe during the endowment.
George F. Richards Diary, June 7, 1922, in Devery S. Anderson ed., The Development of LDS Temple Worship 1846–2000: A Documentary History (Salt Lake City: Signature Books, 2011), 1856
I attended to my duties as usual at the Temple. I had 33 marriages solemnized. I filled an appointment made with the [First] Presidency other brethren being present as follows: Jos[eph] Fielding Smith, Albert W. Davis, Duncan M. McAllister, Willard Young, Israel Call & Patriarch Hyrum G. Smith.
I presented the suggestions of a change in the order of robing and in the wording of the ordinances and lecture which were by vote approved. This order is to place the robe on the left shoulder at the point in the Telestial room when formerly it was placed on the right shoulder, and change [it] onto the right shoulder at that point in the ceremony in the Telestial room where at present it is changed onto the left shoulder-there will be no other changing of the robes. The ceremonies and Lecture will be changed to conform [to this convention]. Full explanation will be given in [the] Temple Historical Record. This will clarify some matters which at present are obscure and will shorten the services.
