Martin Tanner discusses the purpose and meaning of Temple Garments.  The Church of Jesus Christ of Latter-day Saints has sacred clothing, which is not unique. Sacred garments are mentioned in Genesis 3:21 says God made clothing for Adam and Eve. Joseph, who was sold into Egypt, was given a coat of "many priesthood powers" (not many colors). Nuns, priests, ministers and Jewish Rabbis all wear sacred clothing, with meanings, similar to Temple Garments.  When Elijah was taken into heaven, he left his "Mantle" or sacred cloak/coat, which was a symbol of his power as a prophet, to his successor Elsha.
