Ruffle, dishevel (6)
I believe the answer is:
rumple
I believe this clue is a double definition.
'ruffle' is the first definition.
(synonyms)
'dishevel' is the second definition.
(thesaurus)
(Other definitions for rumple that I've seen before include "Make dishevelled" , "Make uneven or wrinkled" , "Dishevel, ruffle" , "Wrinkle, fold or crease" , "Make (eg, bed) untidy" .)
