Naked wearing rubbish silk (7)
I believe the answer is:
tabaret
'silk' is the definition.
(I've seen this before)
'naked wearing rubbish' is the wordplay.
'naked' becomes 'bare' (synonyms).
'wearing' is an insertion indicator.
'rubbish' becomes 'tat' (tat can mean rubbish or poor-quality material).
'bare' placed into 'tat' is 'TABARET'.
(Other definitions for tabaret that I've seen before include "material" , "Beat tar out of upholsterer's silk fabric" .)
