I believe the answer is:
alb
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">priestly garment</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for alb that I've seen before include "Priests robe made in Balbriggan" , "Long white church vestment" , "Priestly garment" , "Priest's long white sleeved vestment" , "the vicar might put on?" .)
