One shrugs off such vulgarity (9)

I believe the answer is:

roughness

'vulgarity' is the definition.
(thesaurus)

'one shrugs off' is the wordplay.
'off' indicates an anagram.
'one'+'shrugs'='oneshrugs'
'oneshrugs' with letters rearranged gives 'ROUGHNESS'.

'such' is the link.

(Another definition for roughness that I've seen is " Hoarse quality".)

I've seen this clue in The Globe and Mail.
