Notice society girl wearing ring (9)
I believe the answer is:
dismissal
'notice' is the definition.
(I've seen this before)
'society girl wearing ring' is the wordplay.
'society' becomes 's' (common abbreviation in names of organisations).
'girl' becomes 'miss' (I've seen this before**).
'wearing' is an insertion indicator.
'ring' becomes 'dial' (I've seen this before).
's'+'miss'='smiss'
'smiss' placed into 'dial' is 'DISMISSAL'.
(Other definitions for dismissal that I've seen before include "Release - marching orders!" , "job loss?" , "sending off" , "Termination of employment" , "ending" .)
