Ladies make perfect models (6)
I believe the answer is:
ideals
'perfect models' is the definition.
(I've seen this in another clue)
'ladies make' is the wordplay.
'make' indicates an anagram.
'ladies' with letters rearranged gives 'IDEALS'.
(Other definitions for ideals that I've seen before include "Morals" , "High standards for ladies" , "Standards of perfection" , "Moral value" , "Ethics" .)
