Practised fitting coats of Parisian (5)
I believe the answer is:
adept
'practised' is the definition.
(both can mean skilful)
'fitting coats of parisian' is the wordplay.
'fitting' becomes 'apt' (I've seen this in other clues).
'coats' indicates putting letters inside.
'of parisian' becomes 'de' ('of' in French).
'apt' enclosing 'de' is 'ADEPT'.
(Other definitions for adept that I've seen before include "Skillful" , "skilled performer" , "Having the required skills" , "Skilful, expert" , "Proficient, skilled" .)
