Some political icons are dressed in rough white cloth (6)
I believe the answer is:
calico
'dressed in rough white cloth' is the definition.
'calico' can be an answer for 'cloth' (calico is a kind of cloth). I'm unsure of the 'dressed in rough white' bit.
'some political icons are' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'CALICO' is hidden within 'political icons are'.
Can you help me to learn more?
(Other definitions for calico that I've seen before include "Given material for dress" , "Unbleached sixteen down cloth" , "spotted in America" , "White cotton fabric" , "Type of cotton cloth" .)
