Printed cotton fabric (6)
I believe the answer is:
chintz
'printed cotton fabric' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chintz that I've seen before include "Curtain material" , "Glazed cotton cloth with printed pattern" , "Colourful fabric" , "Brightly printed cotton fabric" , "Printed multi-coloured cotton fabric" .)
