Lingerie trim (4)
I believe the answer is:
lace
'lingerie trim' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lace that I've seen before include "Delicate fabric woven in an open web" , "Spike - ornamental fabric" , "Flimsy fabric or shoe fasterner" , "Shoe cord" , "Shoe string" .)
