Ladies worried about models of perfection (6)
I believe the answer is:
ideals
'models of perfection' is the definition.
(I've seen this before)
'ladies worried' is the wordplay.
'worried' indicates anagramming the letters.
'ladies' is an anagram of 'IDEALS'.
'about' is the link.
(Other definitions for ideals that I've seen before include "Lofty aspirations for ladies" , "Dreams" , "Ethics" , "Lofty aims for ladies" , "Models of behaviour to aim for" .)
