A surplice (/ˈsɜːrplɪs/; Late Latin superpelliceum, from super, "over" and pellicia, "fur garment") is a liturgical vestment of Western Christianity. The surplice is in the form of a tunic of white linen or cotton fabric, reaching to the knees, with wide or moderately wide sleeves.
It was originally a long garment with open sleeves reaching nearly to the ground. As it remains in the Western Christian traditions, the surplice often has shorter, closed sleeves and square shoulders. Anglicans typically refer to a Roman-style surplice with the Medieval Latin term cotta (meaning "cut-off' in Italian), as it is derived from the cut-off alb. English-speaking Catholics typically do not make the distinction between the two styles and refer to both as a "surplice".
