Standards of perfection (6)
I believe the answer is:
ideals
'standards of perfection' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ideals that I've seen before include "High aspirations for ladies" , "High standards for ladies" , "Ethics" , "Noble aspirations for ladies" , "100%? > 10 out out of 10? > With capital, more would want these" .)
