King of fitted wardrobes (6)
I believe the answer is:
edward
'king' is the definition.
(I know that Edward is King of England)
'of fitted wardrobes' is the wordplay.
'of' indicates a hidden word.
'EDWARD' can be found hidden inside 'fitted wardrobes'.
(Other definitions for edward that I've seen before include "Name of eight kings" , "-- Scissorhands" , "Name Lambert Simnel took when crowned" , "Former prime minister" , "Boy's name" .)
