The Orarion is the distinguishing vestment of the deacon. It is a narrow stole, usually four to five inches wide and about ten feet long, made of brocade with seven crosses embroidered or appliquéd along its length. The deacon wears the orarion over his left shoulder with the front portion draped over his left forearm. He will often take this section in his right hand when leading litanies or drawing attention to a particular liturgical action.
When preparing for Communion, the deacon will tie the orarion around his waist, bringing the ends up over his shoulders (forming a cross in back) and then down in front, tucking them under the section around the waist.
The subdeacon also wears the orarion, but always wrapped around his body in the manner described above.
