Type of tie (5)
I believe the answer is:
ascot
'type of tie' is the definition.
(I know that ascot is a type of necktie)
This is the entire clue.
(Other definitions for ascot that I've seen before include "Where ladies wear new hats" , "Racecourse, home to the Gold Cup since 1807" , "sporting venue" , "Royal Berkshire race-meeting (and fashion show!)" , "Racecourse and cravat" .)
