Dalmatic vs. Sticharion

The dalmatic is a long, wide-sleeved tunic, which serves as a liturgical vestment in the Catholic, Lutheran, Anglican, United Methodist, and some other churches. When used, it is the proper vestment of a deacon at Mass, Holy Communion or other services such as baptism or marriage held in the context of a Eucharistic service.

The outer clerical garb worn by clergy in the Greek Orthodox Church, corresponding to the alb in catholic churches.

The sticharion (also stikharion or stichar; Greek: στιχάριον; Slavonic: стихарь) is a liturgical vestment of the Eastern Orthodox and Eastern Catholic Churches, roughly analogous in function to the alb of the Western Church. The sticharion is worn by all classes of ordained ministers in the Constantinopolitan Rite and comes in two forms: one worn by priests and one worn by deacon and other altar servers.
