There is a type of “costume” you dress in to perform the ordinances in the Temple. This costume is called Temple Clothing. The men wear a little “baker’s hat” thing. As I said there are shoes, ties, belts, aprons, sashes, slacks, shirts, ties and dresses. It is a ceremonial attire worn only during the ceremony.
Then, there is a seperate article of clothing, an undergarment you wear every day under your clothing and next to your skin, to remind you of oaths and covenants you performed in the Temple. These are called “garments of the priesthood.” In the olden days of Mormonism, you were never allowed to take them off. Now they can be removed to bathe, swim or perform in sports. Some couple leave them on even during marital relations.
They were at one time, ankle length, and they have little symbols stitched into the nipples and navel and knee (there used to be symbols at elbow, wrist and ankle too).
Sorry, I meant why wont FR allow a direct link.
