wear the trousers

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

'to be the dominant partner' is the definition.
I can't tell whether this definition defines the answer.

'new star he wrote sure' is the wordplay.
'new' indicates an anagram.
'star'+'he'+'wrote'+'sure'='starhewrotesure'
'starhewrotesure' anagrammed gives 'WEAR THE TROUSERS'.

Can you help me to learn more?

(Other definitions for wear the trousers that I've seen before include "Lead" , "shelter supporting members" , "Be the dominant one" , "Dominate the union" , "dominate partner?" .)
