Dressed in a suit for the country (7)
I believe the answer is:
tunisia
'the country' is the definition.
(Tunisia is an example)
'dressed in a suit' is the wordplay.
'dressed' indicates an anagram ('dress' can mean 'prepare').
'in'+'a'+'suit'='inasuit'
'inasuit' is an anagram of 'TUNISIA'.
'for' acts as a link.
(Other definitions for tunisia that I've seen before include "African state" , "African republic on the Mediterranean coast" , "Somewhere in North Africa" , "Country between Algeria/Libya" , "Suit Ian to be in North African country" .)
