Stout overlayer on inside of coat being the main attraction (10)

I believe the answer is:

headlining

'being the main attraction' is the definition.
(eg headlining a concert)

'stout overlayer on inside of coat' is the wordplay.
'stout overlayer' becomes 'head' (as in the head on a pint of stout).
'on' is a charade indicator (letters next to each other).
'inside of coat' becomes 'lining' (I've seen this before).
'head'+'lining'='HEADLINING'

(Another definition for headlining that I've seen is " Appearing as the star at (a concert)".)

I've seen this clue in The Independent.
