Peignoir trim (4)
I believe the answer is:
lace
'peignoir trim' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lace that I've seen before include "Delicate open-weave fabric" , "Shoe cord" , "Fine open fabric" , "Tear" , "Fortify with spirits; open fabric" .)
