Snogged after party, Jersey-style? (4-6)

I believe the answer is:

crew-necked

'jersey-style?' is the definition.
(a Jersey might have a crew neck)

'snogged after party' is the wordplay.
'snogged' becomes 'necked' (neck can mean to kiss).
'after' says to put letters next to each other.
'party' becomes 'crew' (both can mean a group of people).
'necked' put after 'crew' is 'CREW-NECKED'.

(Another definition for crew-necked that I've seen is " Like a top".)

I've seen this clue in The Guardian.
