Shows off French article in apartments (7)

I believe the answer is:

flaunts

'shows off' is the definition.
('flaunt' can be a synonym of 'show off')

'french article in apartments' is the wordplay.
'french article' becomes 'un' (French for 'a' - the indefinite article).
'in' is an insertion indicator.
'apartments' becomes 'flats' ('flat' can be a synonym of 'apartment').
'un' placed into 'flats' is 'FLAUNTS'.

I've seen this clue in The Telegraph.
