Show a girl's fun (7)

I believe the answer is:

display

'show' is the definition.
(display can mean to show or expose)

'a girl's fun' is the wordplay.
'a girl's' becomes 'Dis' (short for Diane or Diana).
'fun' becomes 'play' (synonyms).
'dis'+'play'='DISPLAY'

(Other definitions for display that I've seen before include "Exhibit, show" , "Reveal" , "Showcase" , "Exhibition" , "Demonstrate, show" .)

I've seen this clue in the Evening Standard.
