Leading couples in casual, light cotton fabric (6)
I believe the answer is:
calico
This might be a double definition.
'leading couples in casual light cotton' is the first definition.
I know that 'cotton' relates to this answer. I also know that both the answer and definition are adjectives
'fabric' is the second definition.
(calico is a kind of fabric)
Can you help me to learn more?
(Other definitions for calico that I've seen before include "Plain cotton cloth, white or unbleached" , "spotted in America" , "Unbleached sixteen down cloth" , "Type of cotton cloth" , "Given material for dress" .)
