Country attire, not right when it's getting worn (5)
I believe the answer is:
gabon
'country' is the definition.
(Gabon is an example)
'attire not right when it's getting worn' is the wordplay.
'attire' becomes 'garb' (both can mean clothing).
'not' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'when it's getting' is a charade indicator (letters next to each other).
'worn' becomes 'on' (as in clothes having clothes on).
'garb' with 'r' removed is 'gab'.
'gab'+'on'='GABON'
(Other definitions for gabon that I've seen before include "W. African republic" , "African country, capital Libreville" , "W. Afr. equatorial state" , "French spoken here" , "state of Africa" .)
