Bridal covering (4)
I believe the answer is:
veil
'bridal covering' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for veil that I've seen before include "Material over face" , "Hide; yashmak" , "Cover, conceal" , "Face-covering for brides and other women" , "Bridal face covering" .)
