Liturgical vestment (3)
I believe the answer is:
alb
'liturgical vestment' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alb that I've seen before include "Priestly garment" , "Priests robe made in Balbriggan" , "Clerical vestment." , "Long white robe worn by Christian priest" , "Long white robe worn by proest" .)
