Wedding wear (4)
I believe the answer is:
veil
'wedding wear' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for veil that I've seen before include "Material over face" , "Yashmak, for instance" , "Face-covering for brides and other women" , "To obscure" , "Hide; yashmak" .)
