Couturier to follow gold (6)
I believe the answer is:
tailor
'couturier' is the definition.
(thesaurus)
'follow gold' is the wordplay.
'follow' becomes 'tail' (I've seen this before).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'tail'+'or'='TAILOR'
'to' is the link.
(Other definitions for tailor that I've seen before include "Seamster" , "Person who cuts clothes" , "man of the cloth" , "One makes suits etc. to measure" , "Fashion" .)
