Fetching new red coat for Idris Elba (9)
I believe the answer is:
desirable
'fetching' is the definition.
(thesaurus)
'new red coat for idris elba' is the wordplay.
'new' indicates an anagram.
'coat for' suggests removing the centre (the letters which coat the word).
'idris' with its centre taken out is 'is'.
'red'+'is'+'elba'='rediselba'
'rediselba' anagrammed gives 'DESIRABLE'.
(Other definitions for desirable that I've seen before include "Alluring" , "Sought-after - rebel aids (anag)" , "Pleasing" , "Worth having" , "handsome maybe" .)
