Neckwear we hear for dandies (5)
I believe the answer is:
beaux
'dandies' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for beaux that I've seen before include "Dudes" , "French boyfriends" , "Old-fashioned boy friends" , "Handsome men" , "male escorts" .)
