A girl more suited for performance (9)

I believe the answer is:

rigmarole

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

'for performance' is the definition.
(I've seen this before)

'a girl more suited' is the wordplay.
'a girl more' can be anagrammed to 'RIGMAROLE'.
But, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for rigmarole that I've seen before include "long, tedious business" , "boring series" , "Elaborate procedure" , "Performance" , "Nonsensical procedure" .)

I've seen this clue in The Guardian.
