Arrange loosely (5)
I believe the answer is:
drape
'arrange loosely' 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 "Screen" , "Pared (anag.)" , "Arrange (cloth) loosely round something" , "Cover loosely with cloth" , "Hang (cloth) loosely" .)
