Dizzy ladies, models (6)
I believe the answer is:
ideals
'models' is the definition.
(I know this)
'dizzy ladies' is the wordplay.
'dizzy' indicates anagramming the letters.
'ladies' anagrammed gives 'IDEALS'.
(Other definitions for ideals that I've seen before include "Ethics" , "Standards of excellence" , "Models, exemplars" , "Models of perfection" , "Models of excellence" .)
