The Kohen Gadol serves in eight vestments and the common Kohen in four: in a tunic, pants, a hat, and a belt. In addition to these, the Kohen Gadol [wore] a breastplate, an ephod, a cloak, and a [golden] plate.  [Wearing] these [eight vestments], they are consulted for [the decision of] the Urim V'Tumim. They are not consulted except for a king, the Court, or for someone whom the public needs.

[On] Yom Kippur eating, drinking, washing [one's body], anointing [one's body with oil], wearing shoes, and cohabitation are prohibited.  The king and the bride may wash their faces, and a new mother may put on shoes; these are the words of R' Eliezer. But the Sages prohibit [this].
