Principles for correct ladies (6)
I believe the answer is:
ideals
'principles' is the definition.
(I've seen this before)
'correct ladies' is the wordplay.
'correct' is an anagram indicator.
'ladies' anagrammed gives 'IDEALS'.
'for' is the link.
(Other definitions for ideals that I've seen before include "Principles to live up to" , "They're perfect" , "Lofty aspirations for ladies" , "Models of excellence" , "Standards of excellence" .)
