Small fashion accessories match nails, perhaps (7)

I believe the answer is:

tiepins

'small fashion accessories' is the definition.
(pins worn with neckties)

'match nails perhaps' is the wordplay.
'match' becomes 'tie' (I've seen this before).
'nails perhaps' becomes 'pins' (nail can mean to pin in place).
'tie'+'pins'='TIEPINS'

I've seen this clue in The Times.
