Appropriate clothing? Not quite (7)
I believe the answer is:
trouser
'appropriate' is the definition.
(I've seen this before)
'clothing? not quite' is the wordplay.
'clothing?' becomes 'trousers' (trousers is a kind of clothing).
'not quite' means to remove the last letter (most but not all of the word).
'trousers' with its final letter removed is 'TROUSER'.
(Other definitions for trouser that I've seen before include "Appropriate" , "Pocket (something)" , "Pocket (slang)" , "For oneself" , "Our rest (anag)" .)
