Attempts to find neckwear? That's about right (5)
I believe the answer is:
tries
'attempts' is the definition.
('try' can be a synonym of 'attempt')
'neckwear? that's about right' is the wordplay.
'neckwear?' becomes 'ties' (I've seen this in another clue).
'that's about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'ties' enclosing 'r' is 'TRIES'.
'to find' is the link.
(Other definitions for tries that I've seen before include "Attempts" , "Scoring moves in rugby" .)
