Party girl’s neckwear (8)
I believe the answer is:
bandanna
'neckwear' is the definition.
(thesaurus)
'party girl's' is the wordplay.
I cannot quite understand how this works, but
'girl' could be 'danna' and 'danna' is found in the answer.
The remaining letters 'ban' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bandanna that I've seen before include "Large coloured handkerchief" , "square" , "Large brightly-coloured handkerchief or neckerchief (variant spelling)" , "Head silk" , "Large and brightly coloured neckerchief" .)
