Piece of neckwear (3)
I believe the answer is:
tie
'piece of neckwear' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tie that I've seen before include "around the neck?" , "Failure to win" , "Gentleman's item of clothing" , "Dead-heat" , "Fasten, link to" .)
