Brown hosiery shade (4)
I believe the answer is:
ecru
'brown hosiery shade' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ecru that I've seen before include "Greyish white" , "Buff or beige" , "light beige" , "Cure (anag) - unbleached linen" , "Neutral colour" .)
