Arrange in folds (5)
I believe the answer is:
drape
'arrange in folds' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for drape that I've seen before include "Cover loosely for padre" , "Cover loosely with cloth" , "Arrange (cloth) loosely round something" , "Cover with a loose cloth" , "Hang (cloth) loosely" .)
