Bit of a looker, one with class (5)
I believe the answer is:
pupil
'bit of a looker' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pupil that I've seen before include "Eye opening" , "Dark centre of the eye" , "School learner" , "that shrinks from brightness" , "Aperture in an eye" .)
