Confused brides refuse (6)
I believe the answer is:
debris
'refuse' is the definition.
(thesaurus)
'confused brides' is the wordplay.
'confused' indicates an anagram.
'brides' with letters rearranged gives 'DEBRIS'.
(Other definitions for debris that I've seen before include "Remains - wreckage" , "Brides among rubble" , "Fragments of rubbish" , "Rubble, lots of broken pieces" , "Detritus, rubbish" .)
