Cloth with uniform colour? (5)
I believe the answer is:
khaki
I believe this clue is a double definition.
'cloth' is the first definition.
(khaki is a kind of cloth)
'uniform colour?' is the second definition.
(I've seen this before)
'with' acts as a link.
(Other definitions for khaki that I've seen before include "Army dress material" , "Drably coloured" , "Military fabric" , "Military clothing colour" , "Dull brown colour" .)
