Close-fitting kit -- things adjusted (9)
I believe the answer is:
skintight
'close-fitting' is the definition.
(similar in meaning)
'kit things adjusted' is the wordplay.
'adjusted' is an anagram indicator.
'kit'+'things'='kitthings'
'kitthings' anagrammed gives 'SKINTIGHT'.
(Other definitions for skintight that I've seen before include "(Of clothes) very closely fitting" , "(Of garment) very close-fitting" , "Body-hugging" , "Clinging" .)
