Argument some used to get fine gauzy fabric (7)
I believe the answer is:
tiffany
'fine gauzy fabric' is the definition.
(type of sheer fabric)
'argument some' is the wordplay.
'argument' becomes 'tiff' (I've seen this before).
'some' becomes 'any' (similar in meaning).
'tiff'+'any'='TIFFANY'
'used to get' is the link.
(Other definitions for tiffany that I've seen before include "US glass designer" , "Girl's name - New York jeweller" , "like a sort of glass" , "fine fabric" , "gauzy fabric" .)
