Giraffe feature (4)
I believe the answer is:
mane
'giraffe feature' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mane that I've seen before include "Long thick hair" , "(Lion's) hair on neck" , "Lion or horse's 10 Across" , "Neck hair of an animal" , "Hair (of lion)" .)
