Witch costume for TV returned looking the worse for wear (7)
I believe the answer is:
haggard
'tv returned looking the worse for wear' is the definition.
I can't judge whether this defines the answer.
'witch costume' is the wordplay.
'witch' becomes 'hag' (synonyms).
'costume' becomes 'gard' (I can't justify this - if you can you should believe this answer much more).
'hag'+'gard'='HAGGARD'
'for' is the link.
Can you help me to learn more?
(Other definitions for haggard that I've seen before include "Gaunt - British author, d. 1925" , "Drawn, careworn" , "Drawn, gaunt" , "Looking tired and unwell" , "Weary and exhausted" .)
