Flaxen fabric (5)
I believe the answer is:
linen
'flaxen fabric' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for linen that I've seen before include "Flax product" , "Fabric woven from flax fibres" , "Bed sheets etc" , "Such paper" , "Lenin (anag) -- fabric" .)
