A green lap-cloth that Mormons don during the Temple Ceremony. It should be representative of the apron Adam and Eve put on themselves after they disobeyed God. It is green. Even though God told them to take off their aprons, and He gave them clothing made out of animal skins, Mormons keep "The Apron of Disobedience" on when they go through the Veil into the Celestial Kingdom. A constant reminder through all the eternities, of their primal disobedience against God's word, their fall from grace, and their shame over their own nakedness.
Brethren and sisters, put on your aprons.
We are instructed to clothe you in the Robes of the Holy Priesthood. Place the robe on your left shoulder. Place the cap on your head with the bow over the right ear, replace the apron, tie the girdle with the bow on the right side, remove the slippers from your feet, and put them in again as part of the temple clothing. You may now proceed to clothe.
