The French try to get fashionable (6)
I believe the answer is:
latest
'fashionable' is the definition.
(thesaurus)
'the french try' is the wordplay.
'the french' becomes 'la'.
'try' becomes 'test' (test is a kind of try).
'la'+'test'='LATEST'
'to get' is the link.
(Other definitions for latest that I've seen before include "hot bit of news" , "State-of-the-art" , "Up-to-the-minute" , "Of most recent date" , "Most recent or most tardy" .)
