Like many white gowns (6)
I believe the answer is:
bridal
'like many white gowns' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bridal that I've seen before include "as new partner in union" , "of marriage" , "Hotel suite for newly-weds" , "Relating to newly married couple" , "Relating to the woman getting married" .)
