VIP with huge fake hair (3,3)

I believe the answer is:

big wig

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

'vip' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'with huge fake hair' is the wordplay.
'with' says to put letters next to each other.
'huge' becomes 'big' (similar in meaning).
'fake hair' becomes 'wig' (I've seen this in another clue).
'big'+'wig' is 'BIG WIG'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
