Prosecutor with face covering: silk? (6)
I believe the answer is:
damask
'silk?' is the definition.
(type of silk)
'prosecutor with face covering' is the wordplay.
'prosecutor' becomes 'D.A.' (District Attorney).
'with' means one lot of letters go next to another.
'face covering' becomes 'mask' (I've seen this in another clue).
'da'+'mask'='DAMASK'
(Other definitions for damask that I've seen before include "Type of table linen" , "Patterned material" , "Figured material" , "Patterned table linen" , "Reversible fabric - type of rose" .)
