Diplomacy over a sari, if torn (6,5)

I believe the answer is:

savoir faire

'diplomacy' is the definition.
(thesaurus)

'over a sari if torn' is the wordplay.
'torn' is an anagram indicator.
'over'+'a'+'sari'+'if'='overasariif'
'overasariif' with letters rearranged gives 'SAVOIR-FAIRE'.

(Another definition for savoir faire that I've seen is " Tact".)

I've seen this clue in the Sydney Morning Herald.
