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

'victoria' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'refined zip?' is the wordplay.
'refined' becomes 'posh' (I've seen this before).
'zip?' becomes 'spice' (both can mean excitement or energy).
'posh'+'spice'='POSH SPICE'

'once' acts as a link.

Can you help me to learn more?

(Other definitions for posh spice that I've seen before include "A footballer's wife" , "Singing star" .)
