Feathery neckwear
I believe the answer is:
boa
'feathery neckwear' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for boa that I've seen before include "Large reptile" , "One covered in scales" , "Snake; fur" , "strangler" , "Long, thin, feathery scarf" .)
