Party has a certain sophistication, perhaps, that denotes their status (11)

'that denotes their status' is the definition.
I know nothing about this answer so I can't judge whether this works.

'party has a certain sophistication' is the wordplay.
'party' becomes 'social' (social can mean a party or event).
'has' is a charade indicator (letters next to each other).
'a certain sophistication' becomes 'class' (I've seen this in another clue. I am not sure about the 'certain' bit.).
'social'+'class'='SOCIALCLASS'

'perhaps' is the link.

Can you help me to learn more?
