Short tunic from the bottom part of Morocco (5)
I believe the answer is:
rabat
'part of morocco' is the definition.
('Rabat' is part of 'morocco')
'short tunic from the bottom' is the wordplay.
'short' means to remove the last letter.
'tunic' becomes 'tabard' (tabard is a kind of tunic).
'from the bottom' says the letters should be written backwards.
'tabard' with its last letter removed is 'tabar'.
'tabar' backwards is 'RABAT'.
(Other definitions for rabat that I've seen before include "Capital of Morocco" , "North African capital" , "N African capital" , "Moroccan city" , "N African city" .)
