Shows off extremely faithful relatives (7)

I believe the answer is:

flaunts

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

'extremely faithful relatives' is the wordplay.
'extremely' says to hollow out the word (remove centre letters).
'relatives' becomes 'aunts' (aunt is a kind of relative**).
'faithful' with its middle removed is 'fl'.
'fl'+'aunts'='FLAUNTS'

I've seen this clue in The Times.
