I'm a little stuck... Click here to teach me more about this clue!

'expert poser' is the definition.
'supermodel' can be an answer for 'poser'. I am not sure about the 'expert' bit.

'some in puzzledom're pushing to bring back' is the wordplay.
'some in' indicates a hidden word.
'to bring back' says the letters should be written backwards.
'ledomrepus' is hidden in the letters of 'puzzledomre pushing'.
'ledomrepus' in reverse letter order is 'SUPERMODEL'.

Can you help me to learn more?

(Other definitions for supermodel that I've seen before include "Catwalk queen" , "celebrity" , "Star of the catwalk" , "Top catwalk strutter" .)
