Character, one on catwalk, one to emulate? (4,5)

Ross

I believe the answer is:

role model

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

'catwalk one to emulate?' is the definition.
I can't tell whether this defines the answer.

'character one' is the wordplay.
'character' becomes 'role' (synonyms).
'one' becomes 'model' (I can't justify this - if you can you should give a lot more credence to this answer).
'role'+'model'='ROLE-MODEL'

'on' acts as a link.

Can you help me to learn more?

(Other definitions for role model that I've seen before include "One looked up to" , "to set an example" , "Exemplar" , "A worthy person" , "someone to look up to" .)

I've seen this clue in The Telegraph.
