Far from posh (5)
I believe the answer is:
seedy
'far from posh' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for seedy that I've seen before include "Out of sorts" , "Not well turned out" , "Run-down, squalid" , "Sordid and disreputable" , "Off-colour" .)
