Liturgical vestments are rich in symbolism and steeped in centuries of Catholic tradition. Their design, color, and usage are not arbitrary but are governed by liturgical texts—most notably the General Instruction of the Roman Missal (GIRM)—and, in some cases, specific norms found in the Code of Canon Law.
