A scarf might cover it (4)
I believe the answer is:
nape
'a scarf might cover it' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nape that I've seen before include "Here's a hairline" , "Back part of the neck" , "Girl personifying France" , "Scrag" , "sofa" .)
