Mocks dried-out enchantress's clothes (7)
I believe the answer is:
derides
'mocks' is the definition.
(deriding is a kind of mocking)
'dried-out enchantress's clothes' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'clothes' says to hollow out the word (remove centre letters) (only the letters which clothe the word remain).
'enchantresss' with its centre taken out is 'es'.
'dried' is an anagram of 'derid'.
'derid'+'es'='DERIDES'
(Other definitions for derides that I've seen before include "Laughs at" , "Mocks, scorns" , "Ridicules" .)
