Luxurious fabrics (6)
I believe the answer is:
satins
'luxurious fabrics' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for satins that I've seen before include "Gives smooth surface" , "Stains on rich cloths" , "Stains on shiny cloths" , "Stains in expensive cloths" , "Smooth shiny cloths" .)
