Truss cedes to party charmer? (10)
I believe the answer is:
seductress
'charmer?' is the definition.
(thesaurus)
'truss cedes to party' is the wordplay.
'to party' indicates an anagram (I've seen 'partying' mean this).
'truss'+'cedes'='trusscedes'
'trusscedes' anagrammed gives 'SEDUCTRESS'.
(Other definitions for seductress that I've seen before include "Temptress" , "Woman who leads astray" , "Siren" .)
