Make up into a form that's perfect (7)
I believe the answer is:
utopian
'that's perfect' is the definition.
(associated in meaning)
'make up into a' is the wordplay.
'make' indicates an anagram.
'up'+'into'+'a'='upintoa'
'upintoa' is an anagram of 'UTOPIAN'.
'form' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for utopian that I've seen before include "Impractically idealistic" , "Fancifully ideal" , "Of ideal perfection (as More's state)" , "Perfectionist reformer" , "Really ideal in perfect fictional country" .)
