Unfashionable job in faraway place (7)
I believe the answer is:
outpost
'faraway place' is the definition.
'unfashionable job' is the wordplay.
'unfashionable' becomes 'out' ('out' can be a synonym of 'unfashionable').
'job' becomes 'post' (post is a kind of job**).
'out'+'post'='OUTPOST'
'in' acts as a link.
(Other definitions for outpost that I've seen before include "isolated stronghold" , "Small camp some distance away from the main army" , "distant location" , "Distant station or branch" , "Remote stronghold" .)
